Multiplying and Dividing
Multiplicand: if 25x2 is the equation, then 25 is the multiplicand
Multiplier: if 25x2 is the equation, then 2 is the multiplier
Dividend: if 30 2 is the equation, then 30 is the dividend
Divisor: If 30 2 is the equation, then 2 is the divisor

Short Division Partial Product
Lattice (Multiplication)
70 (Multiplication)
Short Division is the Steps:
x59
Steps: 1. Draw a square
exact same thing as
The equation is 70x59 2. Split the square into 4 equal parts
Chunking, except the 3. If the equation is 13x24, then write
digits have to be 2 1 and 3 on the top and 2 and 4 on
by 2, 1 by 2, or 1 by 1.First, do 9x0, which equals the side: 1 3
to 0
1, you can do the 2. 9x7=63, but add a 0 to the 2
equation in your back because the 7 is
head! actually 70, so 630 4
Example: 5 divided 3. Then, 5x0=0
4. Then, draw 3 diagonal lines
by 2= 2R3, you can 4. 5x7=35, but add a 0
because 7 is in the tens facing the left:
do it instantly.
place 1 3
5. Add them all up 2
6. Your product is 980
4
Chunking (Division) 5. Start multiplying: 2x3=6, so
Steps: write 06 in the space in between 2
The equation is and 3:
0

1. How many 25s can fit into 53 but
is smaller than that? Answer: 2
(25x2=50)
2. Write 2 on top of the 3, because
you were doing 53, not just 5.
6. 2x1 is to, so write 02 in the spaces
21 next to the one before
7. 3x4=12, so write 12 in the space
below 06, because that’s in between
50 the 3 and 4
38
3. Write 50 under 53 because thats
8. 4x1 is 4, so write 04 in the last
space
what 2x25 is 9. In each space(in between 2
4. Subtract. 53-50=3, so draw a line diagonal lines), write the sum:
and write 3 underneath the line
5. 25 can’t fit into 3, so drag the 8
down so its 38
6. How many 25s can fit into 38? 1, 0 0
0 2 6
so write 1 next to the 2.
7. 38-25=13, and no 25s can fit 0 1
3 4 2
into 13, so you can do
remainder or make the answer 1 2
a decimal(but I’m going to
show you the remainder). The 10. Your product is 312!
quotient is 21R13.
