Anniversary Gifts for Couples With Young Children
When you have young children it is hard to celebrate even important events like your anniversary. As every parent will tell you, finding the time, energy and money to celebrate is not an easy task. Here are a few gift giving ideas for that couple with young children:
Restaurant gift cards make great gifts. These are great because it allows the couple the convenience of using them when they can fit them into the busy schedule. Additionally, restaurants are something that the couple just may not be able to budget with a family in the house. Going out to dinner is the last thing their budget allows for. A babysitting coupon is another great idea. Chances are, with young children in the house, the couple is starved for time alone. They are probably craving time outside the house. They may not be able to afford a sitter or may not be able to find one that they trust. Offering them a babysitting coupon for the anniversary will allow them to spend some much needed quality time together away from the kids.
Grocery gift cards can be a life saver. I know this seems like something not anniversary worthy, but if you have young children at home and you are living in the current economy, chances are making ends meet can be a bit tough at times. Young children are not cheap with diapers, formula and so on. A grocery card can be used with their every day groceries or maybe to buy something they would love to try at home but can't justify in their budget. Every woman would love a cleaning certificate. Whether you do the cleaning or you pay someone else to do it, this is a real treat for parents of young children. Keeping up with the housework can be overwhelming among the everyday stresses of parenthood. If they are parents who work outside the home it can be even more of a blessing to have someone come in and help out with the housework a bit.
Try getting them a hotel voucher. Getting them a hotel, even locally, for an evening might be something they would love. Getting a night out with just the two of them away from the children is a wonderful thing. And not having to worry about having to be home at a certain time can be like a vacation. A credit card style gift card is gaining in popularity. These are wonderful and allow the couple to use the card any place that credit cards are accepted. They can use them for bills or shopping; whatever they need. You can also pay a bill. If they have bills that are due it might be nice if you could pay one of the smaller ones for them to free them up from that burden for one month.
There are a lot of great gifts to get a couple for their anniversary when they have young children in the house. Pay attention to what they need and you will be home free in finding the perfect anniversary gift.

College Graphing Calculator
Many high school mathematics teachers in Canada and America allow their students to use the graphing calculators in class. In calculus courses the graphing calculator is a required part of the student's equipment. Now the notebook comes equipped with the capability of using it as a graphing calculator. The instructors in certain classes such as chemistry or physics ban the calculator because they have the capability of holding the whole periodic table.
The tool is a great instrument to use for the student in learning certain mathematical procedures that can be used in their future careers; however, the student needs to make sure that they are not relying solely on the calculator for their class studies. This could become a source of cheating that would keep the student from learning properly. It is just so easy to rely on this calculator that most students do not even realize that they are not learning the mathematical procedures but instead are depending on the instrument fully for the answers.
Many of the instructors in high schools and colleges require the students to dump information on a regular basis in order to keep things on an even basis during tests. This works out great for the instructors as their students can learn using their calculators and during test time they can use what they learn to find the answers instead of accessing their calculators to bring up the answers. This is a requirement met by most students during their learning process while attending math class.

Using a Scientific Calculator In Mathematics Exams
With exams approaching this is a short article with reminders and advice for anyone about to take a mathematics exam and who will need to use a scientific calculator.The most common calculator problems are:
- setting up the calculator in the right mode
- not being able to find the calculator manual!
- remembering to change calculator modes
- rounding and inaccurate answers
Why Use a Scientific Calculator?
Scientific calculators all use the same order for carrying out mathematical operations. This order is not necessarily the same as just reading a calculation from left to right. The rules for carrying out mathematical calculations specify the priority and so the order in which a calculation should be done - scientific calculators follow the same order. This order is sometimes abbreviated by terms such as BODMAS and BIDMAS to help students remember the order of doing calculations.
1st. Brackets (all calculations within a bracket are done first)
2nd. Operations (eg squaring, cubing, square rooting, sin, cos, tan )
3rd. Division and Multiplication
4th. Addition and Subtraction
Being aware of this order is necessary in order to use a scientific calculator properly. This order should always be used in all mathematical calculations whether using a calculator or not.
Scientific Calculator Check
There are two types of scientific calculator, the most recent type being algebraic scientific calculators. Algebraic scientific calculators allow users to type in calculations in the order in which they have been written down. Older scientific calculators need users to press the mathematical operation key after they have entered the number.
For example to find the square root of nine (with an answer of three) press: [button]
Algebraic scientific calculator: [SQUARE ROOT] [9] [=]
Non algebraic scientific calculator: [9] [SQUARE ROOT] [=]
Both these types of scientific calculator are fine for exams, but make sure you know how to use your own type.
If you are not sure whether you have a scientific calculator or not, type in:
[4] [+] [3] [x] [2] [=]
If you get an answer of 14, then you have a left to right non-scientific calculator.
If you get an answer of 10, then you have a scientific calculator as it has worked out the multiplication part first.
Lost Calculator Manuals
Calculator manuals tend to get lost very easily or you can never find them as an exam is approaching. A frequent request is what can you do if you have lost your calculator's manual? If it is a relatively new model then you can download a copy from the manufacturer's web site. If it is an old Sharp or old Casio calculator manual then you can still find these on the internet. Even with search engines, finding these manuals can take some time - the following link has information about new and old calculator manuals for Casio, Sharp, Hewlett-Packard and Texas Instruments: here.
Calculator Mode
Now that you have your calculator manual you can set your calculator to the correct settings. The standard settings are usually:
COMPUTATIONAL:
(use MODE button - choose normal not stat) NOT: SD or REG
DEGREES:
(use MODE or DRG button) NOT: RAD OR GRAD
NORMAL:
(use MODE or SETUP and arrow keys) NOT: FIX, SCI, ENG
Many calculators have a reset button on the back that can be pressed in using a pen or paper clip if you want the original factory settings.
The most common mistake is to leave your calculator in a previous mode and FORGETTING TO CHANGE IT BACK AGAIN ! (We've all done it, just try to avoid doing it in the exam !)
Common Calculator Mistakes
(a) Pressing the DRG button by mistake and not doing trigonometry questions in DEGREES mode. (If you are doing more advanced work then forgetting to change out of DEGREES mode !).
(b) Borrowing an unfamiliar calculator or getting a new calculator too close to the exam and not being familiar with the keys and how to change modes.
(c) Forgetting to write down and check work. Any exam with a calculator should have a warning on it! It is essential to write down the calculations that you're doing so that you can get method marks. You should also try and double check all calculations in case of pressing a wrong button.
(d) Rounding before the end of a calculation. Store calculations in the memory and use all the decimal places during calculations. If you use a rounded value too soon then you will lose accuracy.
(e) Forgetting to use brackets on division calculations (e.g. when dividing by ALL the bottom part of fraction).
Many calculators are now very powerful and have amazing computational power. Some of the programmable calculators are mini computers. Although they will all calculate 100% accurately every time, unfortunately they are only as good and as accurate as their operator!
It is often the case that candidates perform better without a calculator as it is very easy to make simple mistakes when using one. If you can do so, it certainly helps to have an idea of the rough size of the answer, so that you can see if an answer is sensible or not. It is also a good idea to repeat all calculations just in case you have made a key press error.
