Video Solution

Solution Steps

00:00 Multiplication and division come before addition and subtraction, so we'll start with them
00:13 Let's solve the parts we marked
00:23 We'll use the commutative property to arrange the exercise in a convenient way
00:29 Addition and subtraction are at the same level, so we'll solve from left to right
00:37 And that's the solution!

Step-by-Step Solution

According to the rules of the order of arithmetic operations, we will begin by enclosing the multiplication and division exercises inside of parentheses:

(25:5)+(4×3)5= (25:5)+(4\times3)-5=

We then proceed to solve the exercises in the parentheses:

25:5=5 25:5=5

4×3=12 4\times3=12

We obtain the following:

5+125= 5+12-5=

To finish we solve the exercise from left to right:

5+12=17 5+12=17

175=12 17-5=12

Answer
