Question

Complete the exercise:

530:2×3+10= 5-30:2\times3+10=

Video Solution

Solution Steps

00:00 Division and multiplication before addition and subtraction - solve from left to right
00:20 Addition and subtraction - from left to right

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:

545+10= 5-45+10=

Finally we solve the exercise from left to right:

545=40 5-45=-40

40+10=30 -40+10=-30

Answer

-30
