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

The order of operation rules are:

**Rule 1:** Start with calculations inside brackets or parentheses.

**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

Based on the rules above, start with multiplication.

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.

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.

Thank you!

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

PEMDAS:

Please (Parentheses)

Excuse (Exponents)

My (Mult.)

Dear (Div.)

Aunt (Addition)

Sally (Subtraction)

Very Good!

Thanks for sharing this!

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.

GEMS

Groupings

Exponents/Square Roots

Multiplication/Division

Subtraction/Addition

Each one you do you also have to do the opposite item at the same time.
