Multiplication and division - Examples, Exercises and Solutions

According to the order of operations, both addition and subtraction can be solved from left to right. So, first subtract 3 from 9:

$9:3=3$

Then add 2 to the result:

$3+2=5$

Therefore, the correct answer is:

$5$

According to the order of operations, multiplication should be performed before addition. So, first calculate the multiplication:

$5 \times 3 = 15$

Then add 2 to the result:

$2 + 15 = 17$

Therefore, the correct answer is:

$17$

According to the order of operations, you should first calculate the multiplication, then the addition:

$4 \times 2 = 8$

Then add the result to 3:

$3 + 8 = 11$

According to the rules of the order of operations, the exercise which contains both multiplication and division should be solved from left to right.

$30:5=6$

$6\times2=12$

First, perform the division:

$6 / 2 = 3$

Then add 5:

$3 + 5 = 8$
