1

Understand the problem

Complete the exercise:

5−30:2×3+10= 5-30:2\times3+10=

2

Step-by-step solution

According to the rules of the order of arithmetic operations, we must first place the multiplication and division exercises within parentheses:

5−(30:2×3)+10= 5-(30:2\times3)+10=

We then solve the exercise inside of the parentheses from left to right:

30:2=15 30:2=15

15×3=45 15\times3=45

We obtain the following exercise:

5−45+10= 5-45+10=

Finally we solve the exercise from left to right:

5−45=−40 5-45=-40

−40+10=−30 -40+10=-30
