Question 1

A numerical expression is evaluated as shown. In which step does the first mistake appear?

2 x (4 x 3 + 2) - 1

Step 1:  2 x (12 + 2) - 1

Step 2:  2 x 14 - 1

Step 3:  2 x 13

Step 4:  26

Question 2

A numerical expression is evaluated as shown. In which step does the first mistake appear?

(10 x 3 - 5) + 2 x (5 + 4 x 5)

Step 1: (30 - 5) + 2 x (9 x 5)

Step 2: 25 + 2 x (45)

Step 3: 25 + 90

Step 4: 115

Question 3

Terone baked muffins, m, for his bake sale. He burned 12 muffins and had to throw them away. He sold 30 muffins and split the rest between 3 friends. Which equation represents the situation?

(m - 12 - 30) x 3 = 54

(m - 12 - 30) / 3 = 6

(42 - m) / 3 = 6

(m + 42) / 3 = 54

Question 4

Sharice practiced her clarinet for 1 hour on Monday night. On Tuesday, she practiced half as long as on Monday night. She repeated this pattern for 3 weeks. Which expression can be used to calculate how many hours Sharice practiced her clarinet?
Remember "half" = 0.5

1 + 0.5 x 3

1 + 1.5 x 3

1 + (0.5 x 3)

(1 + 0.5) x 3
