1) 64 divide -4 = -16

2) -144 divide (-9) = 16

3) Simplify -9 and a small 2 = -81

4) Simplify (-3) and a small 3 = -27

5) Add -4/11 + 5/11 = 1/11

6) subtract 5/11- [-3/11] = 8/11

7) multiply [-7/8] • [-2/4] = 7/16

8) divide -3.5 -5.6 = -0.63

9) classify the given number.

-4/9 = Real

10) find the expression.

-128 divide 4 and small2 + 6-1 = -15

11) find the value of expression.

3•45 divide 9 - 2 (10 -6) - 4 divide 2 = -13

Please check my work and explain what I have done wrong.

3) ( - 9 ) * ( - 9 ) = 81

When you square a negative number you ALWAYS get a positive result.

8) -3.5 / -5.6 = -0.625

10) -128 / ( 4 * 4 ) = -128 / 16 = -8

-128 / ( 4 * 4 ) + 6 - 1 = - 8 + 6 + 1 = -3

11) 3 * 45 = 135

135 / 9 = 15

[ 2 ( 10 - 6 ) - 4 / 2 ] = ( 2 * 4 - 4 ) / 2 =

(8 - 4 ) / 2 = 4 / -2 = 2

( 3 * 45 /9 ) - [ 2 * ( 10 - 6 ) - 4 ] / 2 =

15 - 2 = 13
