PEMDAS- Parentheses, Exponents, Multiplication and Division, Addition and Subtraction
Can Microsoft Excel do division?
Microsoft Excel is for numerical analysis and manipulation so it can do any mathematical calculations, including division. You use the / as the division symbol. You can use numbers, but more commonly cell references. For example: =A10/A12 =A10/40 =200/A12
When doin math calculations which one comes first?
BODMAS B=Brackets O=Of D=Division M=Multiplication A=Addition S=Subtraction So, division comes first, then multiplication, then addition and finally subtraction.
Why do you need to find the reciprocal of the divisor when dividing a fraction?
It is not just in fractions. In general, division can be defined as multiplication by the reciprocal. For example, dividing by 5 is the same as multiplying by 0.2. However, it is mainly in calculations with fractions that this is normally used as a practical way of doing the calculations.

First device used for mathematical calculations?
Suan-pan tray, which developed in China around 200BC. Suan-pan is an abacus for various calculations including counting, addition, subtraction, multiplication, division, square roots and cube roots. This is recored earliest device use for mathematical calculation
What is the abacus good for?
mostly addition & subtraction. you can do multiplication & division to but they are about an order of magnitude more difficult. even more complicated calculations can be done, if you learn how, but they rapidly become prohibitively difficult to do.
Write two order-of-operation problems?
The two orders of operation are: Perform all calculations inside the parentheses first. Perform all multiplication and division starting from left to right.
