Video Solution

Step-by-Step Solution

First, let's look at the number line and locate each letter:

A+L=4+7=3 A+L=-4+7=3

GE=20=2 G-E=2-0=2

H+C=3+(2) H+C=3+(-2)

BD=3(1) B-D=-3-(-1)

Then let's solve the remaining exercises remembering the rules:

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

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

Therefore:

H+C=3+(2)=32=1 H+C=3+(-2)=3-2=1

BD=3(1)=3+1=2 B-D=-3-(-1)=-3+1=-2

A+L is the largest value.

Answer

A+L A+L
