Here are the solutions to the problems on your worksheet. Remember the rule: always do multiplication and division
before addition and subtraction, unless there are parentheses (brackets). If there are parentheses, do those first!
1.
15 + 6 - 13 =
* First, add: $15 + 6 = 21$
* Then, subtract: $21 - 13 = 8$
* Answer:
8
2.
21 + 32 x 2 =
* Multiply first: $32 \times 2 = 64$
* Then add: $21 + 64 = 85$
* Answer:
85
3.
23 - 16 ÷ 2 =
* Divide first: $16 \div 2 = 8$
* Then subtract: $23 - 8 = 15$
* Answer:
15
4.
50 - 12 x 4 =
* Multiply first: $12 \times 4 = 48$
* Then subtract: $50 - 48 = 2$
* Answer:
2
5.
(14 + 7) x 2 =
* Do the parentheses first: $14 + 7 = 21$
* Then multiply: $21 \times 2 = 42$
* Answer:
42
6.
12 x 3 - 10 =
* Multiply first: $12 \times 3 = 36$
* Then subtract: $36 - 10 = 26$
* Answer:
26
7.
2 + 2 x 5 - 7 =
* Multiply first: $2 \times 5 = 10$
* Now the problem is: $2 + 10 - 7$
* Add: $2 + 10 = 12$
* Subtract: $12 - 7 = 5$
* Answer:
5
8.
14 - 10 2 =
* Divide first: $10 \div 2 = 5$
* Then subtract: $14 - 5 = 9$
* Answer:
9
9.
20 + 12 - 24 =
* There is no multiplication or division, so just go from left to right.
* Add: $20 + 12 = 32$
* Subtract: $32 - 24 = 8$
* Answer:
8
10.
(12 - 9) x 6 =
* Do the parentheses first: $12 - 9 = 3$
* Then multiply: $3 \times 6 = 18$
* Answer:
18
