Quiz Review (BEDMAS, One-Step Equations, Patterning)

Word Stuff

100

Give the correct order of operations.

Parentheses, Exponents, Multiplication OR Division, Addition OR Subtraction

200

Why is it important to know PEMDAS as a mathematician?

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

300

What is the acronym we use to remember the correct Order of Operations?

BEDMAS

400

Tell what 5 ³ really means.

It means 5 x 5 x 5

500

The problem was 20 - 5 x 2 + 3. My answer was 33. What did I do wrong?

I went from left to right without using the correct order of operations.

Fix my Mistake

100

9 - 3 x 2=12

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

200

5 ² + 1=11

5 ² = 25, not 10. Correct Answer is 26.

300

3² - 6 = 0

3 ² = 9, not 6. Correct answer is 3

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.

Pattern Rules

100

2, 4, 6, 8...

Start at 2 and add 2 each time.

200

3, 6, 12, 24, 48

Start at 3 and double each time.

300

1, 1, 2, 3, 5, 8

Start with 1, 1 and add the two previous terms each time. 

400

500, 100, 20, 4

Start at 500 and divide by 5 each time. 

500

4, 7, 13, 25, 49

Start at 4 and multiply the previous number by 2 then subtract 1. 

One-Step Equations

100

x + 3 = 5

x = 2

200

3x = 15

x = 5

300

40 - x = 28

x = 12

400

x/5 = 20
