Step-by-step explanation:
vSome people seem to have real difficulty learning their multiplication facts. Parents, teachers, and students have written to Dr. Math asking for help with learning their multiplication tables (see some of the best answers from our archives). For an enjoyable twist, see also Russian Peasant Multiplication.
There are many ways to help us remember such things, but what works best will be different for different people. For example, you can try to remember something by saying it repeatedly, writing it, acting it out, representing or drawing it, making up a game or story or song about it, and so on. Usually, the more ways you use to connect it to your brain, the easier it is to remember it.
Here's how this might work with multiplication facts.
You can make a multiplication table.
Since 1 times any number is just that number, we can leave the 1's off. Multiplying a number on the left by a number on the top gives you the number ("product") where the row (across) meets the column (down). Here's 4 x 7 = 28 (shown in red):
x | 2 3 4 5 6 7 8 9 10 11 12
--+------------------------------------------
2 | 4 6 8 10 12 14 16 18 20 22 24
|
3 | 6 9 12 15 18 21 24 27 30 33 36
|
4 | 8 12 16 20 24 28 32 36 40 44 48
|
5 |10 15 20 25 30 35 40 45 50 55 60
|
6 |12 18 24 30 36 42 48 54 60 66 72
|
7 |14 21 28 35 42 49 56 63 70 77 84
|
8 |16 24 32 40 48 56 64 72 80 88 96
|
9 |18 27 36 45 54 63 72 81 90 99 108
|
10 |20 30 40 50 60 70 80 90 100 110 120
|
11 |22 33 44 55 66 77 88 99 110 121 132
|
12 |24 36 48 60 72 84 96 108 120 132 144
Some people describe a row (or column) as "skip counting," so the row beginning at 5 is the row of "5 times" facts, or "skip counting by 5s."
x | 2 3 4 5 6 7 8 9 10 11 12

5 |10 15 20 25 30 35 40 45 50 55 60
These "times tables" can be memorized as a smaller chunk by themselves. Sometimes making a song or story helps you learn them. SchoolHouse Rock (select Multiplication, or see Schoolhouse Rock Lyrics) provides a good example.
Finding patterns
A good way to learn multiplication facts is to look for other patterns in the table. For example, notice that (4 x 7) is the same as (7 x 4). You can represent this
Answer:
1% = 3264/100
= 32.64
121/2% = 32.64×121/2
121/2% = 1,974.72
