part1) Choose #s

1) 0.6

2) -7

3) 5

4) -1/2

part 2). Compare #s

1) 0.6>-1/2

2) 5>-7

3)-7< -1/2

4)0.6>-7

5) 5>-1/2

6)0.6<5

Order from least to greatest

-7, -1/2,0.6,5

Number line

----7----------1/2-0-0.6-------5---------------

Part 3). Absolute value

1)[-7]+0.6 = 7.8

2) 5/[0.6]=.12

3) [-1/2]*5=2.5

4) [-1/2]-0.6=.10

Explanation: The absolute value is the distance a number is from zero.

Example: -7 is 7

Part 5) Operations with integers

Addition: 1) [-7]+ 5=12

2) -10+(5)=5

Subtraction: 1) (-20)-(-12)=-8

2) 5 -(4)=1

Multiplication: 1). (6.5)*7=45.5

2) 12*(5.5)=6.6

Division : 1) 240/(80)=30

2) (360)/6=60

Part5) Real life math problems

1). (12-2)*(-7*4)=-280

2). 250/10+(11*12)=157

3). (8*7)-(150-50)=44
