Evaluate the Expression: 10-(-2)-3×4-(-4) Using Order of Operations

Question

10(2)3?4(4) 10-(-2)-3?4-(-4)

Video Solution

Step-by-Step Solution

First we need to remember the following laws:

(x)=+x -(-x)=+x

+(x)=x +(-x)=-x

We'll solve the left side first.

Let's rewrite the expression in the appropriate form:

10+23= 10+2-3=

Next, we'll solve the exercise from left to right:

10+2=12 10+2=12

123=9 12-3=9

Now let's solve the right-hand side, using the laws we reminded ourselves of earlier.

We'll then rewrite the expression in the appropriate form and solve:

4+4=8 4+4=8

Since the left-hand side is larger, the appropriate sign will be:

9 > 8
