BEMDAS (Order of Operations)

Word Stuff

100

Give the correct order of operations.

Brackets, Exponents, Division OR Multiplication, Addition OR Subtraction

200

Why is it important to know BEMDAS as a mathematician?

So everyone can solve every problem the same (correct) way.

300

Which operation is not in the curriculum in Grade 6 (or 7)?

Exponents.

400

Tell what 5 ³ really means.

It means 5 x 5 x 5

500

True or False? 

I do Addition first, then Subtraction when solving an equation because that is the order they appear in BEDMAS

False.

I do Addition OR Subtraction in the order they appear, working left to right.

Fix my Mistake

100

9 - 3 x 2=12

Correct answer is 3. Do x then -, not - then x.

200

2 x (5  + 1) =11

Correct answer is 12. 

5 + 1 first, then multiply by 2. Not 2 x 5 first - (you can't pull a number out of a bracket). 

300

3 + 12 x 2 - 6 = 24

Correct answer is 19. 

12 x 2 first (not 3 + 12 first)

400

4 + 5 + 7 - 3 x 2 = 26

You need to follow PEMDAS and do x first. Correct answer is 10.

500

10 ³ = 30

10 ³ = 10 x 10 x10, which is 1000, not 30.
