### How Adding Doubles is same as Multiplying by Two?

When we multiply a number by 2 we are just doubling the number. These two actions are similar and we can prove the same by having a glance at the below modules.

**Double the Numbers and Multiply by 2 from 0-10
**

0+0 = 0 or 0*2 =0 1+1 = 2 or 1*2 = 2 2+2 = 4 or 2*2 = 4 3+3 = 6 or 3*2 = 6 4+4 = 8 or 4*2 = 8 5+5 = 10 or 5*2 = 10 6+6 = 12 or 6*2 = 12 7+7 = 14 or 7 *2 = 14 8+8 = 16 or 8 *2 = 16 9+9 = 18 or 9*2 = 18 10+10= 20 or 10*2 = 20 |

**Double the Numbers and Multiply by 2 from 11-20**

11+11 = 22 or 11*2 = 22 12+12 = 24 or 12*2 = 24 13+13 = 26 or 13*2 = 6 14+14 = 28 or14*2 = 8 15+15 = 30 or 15*2 = 30 16+16 = 32 or 16*2 = 32 17+17 = 34 or 17 *2 = 34 18+18 = 36 or 18 *2 = 36 19+19 = 38 or 19*2 = 38 20+20= 40 or 20*2 = 40 |

**Double the Numbers and Multiply by 2 from 21-25
**

21+21 = 42 or 21*2 = 42 22+22 = 44 or 22*2= 44 23+23 = 46 or 23*2 = 46 24+24 = 48 or 24*2 = 48 25+25 = 50 or 25*2 = 50 |

### Examples on Addition of Doubles

**Example 1.**

Mary has 4 balls and James has double the balls mary has. Find How many Marbles does James have?

**Solution:
**No. of balls Mary has = 4

James has double the balls mary has i.e. 4+4 or 4*2 = 8

Therefore, James has 8 Marbles in total.

**Example 2.
**Add 3+4 using doubles?

**Solution:**

The Number 4 is more than 3 and we can write 4 as 3+1

As we know the double of 3 is 6.

Therefore, the sum of 3+4 would be one more than the double i.e. 6+1=7

Thus, the sum of 3+4 is 7

**Example 3.
**Find the Sum of 6+5 using doubles?

**Solution:**

The Number 5 is one less than 6 and we can write 5 as 6-1

As we know the double of 6 is 12.

Thus, the sum of 6+5 would be one less than the double i.e. 12-1

Thus, the sum of 6+5 is 11

**Example 4.
**What is 4+4 =?

**Solution:**

We know 4+4 or 4*2= 8

Thus, the Double of 4 is 8
