Exercise #19

Choose the expression that has the largest value.

AAA-5-5-5BBB-4-4-4CCC-3-3-3DDD-2-2-2EEE-1-1-1FFF000GGG111HHH222III333JJJ444KKK555LLL666MMM777NNN888

Video Solution

Step-by-Step Solution

Let's look at the number line and locate each letter:

H+D=2+(2) H+D=2+(-2)

BCD=4(3)(2) B-C-D=-4-(-3)-(-2)

G+I=1+3=4 G+I=1+3=4

F=0 F=0

Then we can solve the remaining exercises, remember the rules:

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

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

Therefore:

H+D=2+(2)=22=0 H+D=2+(-2)=2-2=0

BCD=4(3)(2)=4+3+2=1+2=1 B-C-D=-4-(-3)-(-2)=-4+3+2=-1+2=1

G+I is the largest.

Answer

G+I G+I

Exercise #20

Choose the expression that represents the largest value.

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.
