1) What is the symbol for addition? +

2) Give the symbol for subtraction -

3) Write a symbol for multiplication. * or x or ( )

4) What are the symbols for division? / or

5) If you are not using WORD’s superscript to write an exponent, what symbol should you use? ^

6) If you are not using WORD’s superscript to show square root, what letters and symbols could you use in its place? sqrt ( )

7) If you are not using WORD’s superscript to show cube root, what letters and symbols could you use in its place? cubrt ( )

8) Simplify: = 16

9) Find: = 5

10) Evaluate: = -25

11) Compute: = 25

12) Combine:

a) 6 + ( -11) = -5

b) (-10) + 3 = -7

c) (-2) + (-5) = -7

d) 10 + 7 = 17

e) 6 - 12 = -6

f) (-5) - 2 = -7

g) ( -4) - ( -3) = -1

h) 9 - ( -6) = 15

13) Complete the sentences:

a) The sum of two positive numbers = positive number.

b) The sum of two negative numbers = negative number.

c) The product of two positive numbers = positive number.

d) The product of two negative numbers = positive number.

e) The product of a positive number and a negative number =

negative number.

f) The quotient of two positive numbers = positive number.

g) The quotient of two negative numbers = positive number.

h) The quotient of a positive number and a negative number =

negative number.

i) The number zero is not a positive number.

j) The number zero is not a negative number.

14) Simplify:

a) ( 4) ( 5) = 20

b) ( -2) ( 4) = -8

c) ( -3) ( -5) = 15

d) ( 7) ( -8) = -56

e) = 2

f) = 7

g) = -6

h) = -7

i) = 0

j) = undefined
15) Solve for x:

a) x + 8 = 10 x + 8 - 8 = 10 - 8

To undo the adding of 8, we do the opposite operation to both sides of the equation ( the = sign). We, therefore, subtract 8 from both sides of the equation ( the = sign). x = 2

b) x - 3= 11

x - 3 + 3 = 11 + 3

To undo the subtracting…
