MULTI-DIGIT MULTIPLICATION

5 2 5 3 2 1 Erase your "carried" numbers so you dont get confused! 373 First, we must put a place holder under the ones. Erase your "carried" numbers so you dont get confused. Multiply and "CARRY" - Just like addition! Start with the ones. Do a 'SPRAY'. Now do the tens- Use a 'SPRAY'! We must put place holders under the ones and tens. x 875 Now let's do the hundreds using a "spray". 1 1 18 6 5 + 1 Now add! 26 1 1 29 8 4 3 2 6 3 7 5

Multiply and "CARRY" - Just like addition! Start with the ones. Do a 'SPRAY'. Now do the tens- Use a 'SPRAY'! We must put place holders under the ones and tens. x 225 Now let's do the hundreds using a "spray". 2 1 18 4 5 + 1 Now add! 7 3 8 7 3 8 8 3 2 5

Now take 5 minutes to do these problems: 62x48= 643x25= 246x 174= 438x 347= 752x100= .

7
ANSWERS 62x48= 2976 643x25=16,075 246x 174=42,804 438x 347=151,986 752x100=75,200 .

**Dividing Difficult Large Numbers**

31) 1719 31 will not go into 1 31 will not go into 17 31 will go into 171

10
**Dividing Difficult Large Numbers**

31) 1719 To figure what your first number will be cover the 1 in 31 & the 1 in 171.

11
**Dividing Difficult Large Numbers**

31) 1719 Now ask how many 3’s will go into 17.

12
**Dividing Difficult Large Numbers**

5 31) 1719 Be sure to put that number directly above the 1 not the 7.

13
**Dividing Difficult Large Numbers**

5 31) 1719 Now multiply the 5 x 31 and place it under the 171.

14
**Dividing Difficult Large Numbers**

5 31) 1719 155 31 x5 16 9 155

15
**Dividing Difficult Large Numbers**

5 31) 1719 155 16 9 Now cover up the 1 in 31 & the 9 in 169

16
**Dividing Difficult Large Numbers**

5 31) 1719 155 16 9 Ask how many 3’s will go into 16.

17
**Dividing Difficult Large Numbers**

5 5 31) 1719 155 16 9 Place that number next to the 5 in your quotient.

18
**Dividing Difficult Large Numbers**

5 5 31) 1719 155 16 9 Now multiply 31 x 5.

19
**Dividing Difficult Large Numbers**

5 5 31) 1719 155 16 9 Subtract & your answer is 55 R14 155 14

20
**Dividing Difficult Large Numbers**

5 5 31) 1719 155 31 X 5 169 9 155 155

21
**Check It Using the Inverse of Division:**

Multiply the divisor by the quotient. X 55 155 +1550 1705 Add Remainder to the product Your answer should math the original dividend
