Basic Arithmetic Operations

 

Addition

1. Positive no + Positive no = Positive no , Eg: 6 + 5 = 11
2. Negative no + Negative no = Negative no , Eg: -4 + -7 = -11
3. Negative no = Positive no = Difference of the nos and sign of greater no , Eg: +8 + -10 = -2

Multiplication

1. Positive no x Positive no = Positive no , 6 x 3 =18
2. Negative no x Negative no  = Positive no , -2 x -6 = 12
3. Positive no  x Negative no = Negative no , 5 x -6 = -30
4. Negative no  x Positive no = Negative no , -8 x 2 = -16

Division

1. Positive no ÷ Positive no = Positive no , 18 ÷ 3 = 6
2. Negative no ÷ Negative no  = Positive no , -12 ÷ -6 = 2
3. Positive no  ÷ Negative no = Negative no , 30 ÷ -6 = -5
4. Negative no  ÷ Positive no = Negative no , -16 ÷ 2 = -8
