Addition 0+0=0 0+1=1 0+2=2 0+3=3 0+4=4 0+5=5 1+0=1 1+1=2 1+2=3 1+3=4 1+4=5 1+5=6 2+0=2 2+1=3 2+2=4 2+3=5 2+4=6 2+5=7 3+0=3 3+1=4 3+2=5 3+3=6 3+4=7 3+5=8 4+0=4 4+1=5 4+2=6 4+3=7 4+4=8 4+5=9 5+0=5 5+1=6 5+2=7 5+3=8 5+4=9 5+5=10 6+0=6 6+1=7 6+2=8 6+3=9 6+4=10 7+0=7 7+1=8 7+2=9 7+3=10 8+0=8 8+1=9 8+2=10 9+0=9 9+1= =10

Subtraction Subtraction is the difference of two numbers. When you subtract you take something away. If you have 5 apples and you take away 2 you are left with three. Sum Sense

Multiplication TWO 0 * 2 = 0 1 * 2 = 2 2 * 2 = 4 3 * 2 = 6 4 * 2 = 8 5 * 2 = 10 6 * 2 = 12 7 * 2 = 14 8 * 2 = 16 9 * 2 = 18 THREE 0 * 3 = 0 1 * 3 = 3 2 * 3 = 6 3 * 3 = 9 4 * 3 = 12 5 * 3 = 15 6 * 3 = 18 7 * 3 = 21 8 * 3 = 24 9 * 3 = 27 Multiplication is repeated addition. 4*7 is simply =28 The final answer of a multiplication problem is the product.

Division Separates things into equal portions. When dividing 8 by 2, it separates 8 into 2 equal portions of 4. Matho TWO 0 ÷ 2 = 0 2 ÷ 2 = 1 4 ÷ 2 = 2 6 ÷ 2 = 3 8 ÷ 2 = 4 10 ÷ 2 = 5 12 ÷ 2 = 6 14 ÷ 2 = 7 16 ÷ 2 = 8 18 ÷ 2 = 9 THREE 0 ÷ 3 = 0 3 ÷ 3 = 1 6 ÷ 3 = 2 9 ÷ 3 = 3 12 ÷ 3 = 4 15 ÷ 3 = 5 18 ÷ 3 = 6 21 ÷ 3 = 7 24 ÷ 3 = 8 27 ÷ 3 = 9

Fractions Whole number: the numerator and the denominator are equal. (Ex: 3/3=1) Proper fractions: the numerator is smaller that the denominator. (Ex: 5/6) Improper Fractions: the numerator is bigger than the denominator. (Ex: 8/5) Mixed Numbers: A whole number and a fraction. (Ex: 8/5=1 & 3/5) Cookies For Grampy
