YES!! You should definitely use a calculator with our courses.
Please see our Calculator Buying Guide attached below. There are several recommended, but please note that the calculator must be a SCIENTIFIC calculator. There are two important reasons for this:
Scientific calculators allow you to enter numbers in scientific notation. When you are doing math with scientific notation, that makes things a lot easier.
Also, scientific calculators understand order of operations. Thus, you can enter
1 + 3×2
into such a calculator and get the proper answer, which is 7, because the calculator knows that it must multiply before it adds. A non-scientific calculator will give you an answer of 8 because it will add 3 to 1 and THEN multiply by 2, which is not correct.
