REVIEW FOR NEGATIVES,
POSITIVES, AND FRACTIONS
Addition
Positive + Positive
Negative + Negative
Positive + Negative
Negative + Positive
2 + 4 = 6
- 2 + (-4) = -6 2 + (-4) = -2 -2 + 4 = 2
Subtraction
Positive – Positive Negative – Negative Positive – Negative Negative – Positive
2 - 4 = -2
- 2 - (-4) = 2 2 - (-4) = 6 -2 - 4 = -6
Multiplication
Positive • Positive Negative • Negative Positive • Negative Negative • Positive
2 • 4 = 8
- 2 • (-4) = 8 2 • (-4) = -8 -2 • 4 = -8
Division
Positive ÷ Positive Negative ÷ Negative Positive ÷ Negative Negative ÷ Positive
2 ÷ 4 = ½
- 2 ÷ (-4) = ½ 2 ÷ (-4) = -½ -2 ÷ 4 = -½
Adding and Subtracting Fractions
Adding Fractions Subtracting Fractions
1/5 + 2/5 = 3/5 1/5 – 2/5 = -1/5
Multiplying Fractions
Fraction • Whole Number (Integer) Fraction • Fraction
1/5 • 2 =1/5 • 2/1 = 2/5 1/5 • 2/5 = 2/25
Dividing Fractions
Fraction ÷ Whole Number Whole Number ÷ Fraction Fraction ÷ Fraction
1/5 ÷ 2 = 1/5 • 1/2 = 1/10 2 ÷ 1/5 = 2 • 5/1 = 10 1/5 ÷ 2/5 = 1/5 • 5/2 = 5/10 = 1/2
