# Basic Math – Order of Operation Practice ### Order of Operation – Rules, Examples and Practice Questions

The order of operation rules are:

Rule 2: Then, solve multiplications and division, from left to right.
Rule 3: Finally, additions and subtraction, from left to right.

## Example 1

Solve 16 + 5 x 8

This gives: 16 + 40 = 56

Note that if the rule was not followed, and addition was done first, the answer would be different and incorrect, as in,

16 + 5 x 8

21 x 8 = 168 (wrong answer)

## Example 2

3 +(35 – 21) x 2

Solve the problem inside the brackets first. Then multiplication, and finally addition.

3 + (35 – 21) x 2
3 + (14) x 2
3 + 28
= 31

BIMDAS rule. Easy to remember.

• June 4, 2017

I think it is PIMDAS – Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. … The original order of operations in some countries was BODMAS, which stands for Brackets, Orders or Powers, Division, Multiplication, Addition, Subtraction.

BEDMAS=brackets, exponents, division, multiplication, addition then subtracting

I am useless with mathematics but need to practice before I start a nursing degree. Thanks for explaining how to do these kind of sums, helped me a lot.
