Question
231 × 4 =_________.
- 220
- 400
- 924
- 2200
Hint:
Here perform the multiplication between 231 x 4 . It says that the add 4 times 231 or add 231 times 4. You can do both to find the answer.
The correct answer is: 924
Here we have to find the value of 231 x 4.
We know that this is multiplication of 231 x 4 but we solving this question by addition.
It says that the addition of number 231 into 4 time ,
Now , we can write that
231 x 4 = 231 + 231 +231 + 231
Add the RHS,
231 x 4 = 924
Therefore, solution of 231 x 4 is 924.
The correct answer is 924 (option (c)).
Or,
231 = 200 + 30 + 1
231 × 4 = (200 4) +(30 × 4) +(1 × 4)
= 800 + 120 +4
= 924
We can apply same procedure in any kind of multiplication. If a x b is given then it says the addition a into b time or vice verse. If this multiplication comes under certain table then you can write direct answer.

There are 5 photographers who take pictures for the city newspaper. For yesterday's issue, each photographer took 188 pictures. The total pictures were there in all?
The inverse operation of multiplication is division. For example, since 4 multiplied by 3 equals 12, 12 divided by 3 equals 4. Indeed, multiplication by 3, followed by division by 3, yields the original number. The division of a number other than 0 by itself equals 1.
