63 + 31 =​

Answer 1

Answer:

1) 59

2) 94..............….....

Answer 2

Answer:

$37 + 22 = 59$

$63 + 31 = 94$

Step-by-step explanation:

We have to break the numbers and add. Breaking means splitting the numbers in such a way that Adding them becomes easy.

As we know the numbers having zero at units place is easier to add so we will break the numbers in such a way that one of the split number becomes a multiple of 10.

1) First Sum

The nearest number to 37 which is a multiple of 10 is 30. So breaking 37 into two parts 30 and 7,

$37 = 30 + 7$

Similarly for 22, we will break it into 20 and 2

$22 = 20 + 2$

Now adding them,

$37 + 22 = 30 + 7 + 20 + 2$

While adding we will add 30 and 20 separately and 7 and 2 separately and then we will add the numbers obtained by adding them. Such a way is easier for addition.

$= 30 + 20 + 7 + 2$

$= 50 + 9$

$= 59$

Therefore 37+22= 59

2) Second Sum

Following the same process for 63+31,

$63 + 31 = 60 + 3 + 30 + 1$

$= 60 + 30 + 3 + 1$

$= 90 + 4$

$= 94$

Therefore 63+31 = 94

Note:

This method is very useful for Mental calculation.

So the Final Answer is

$37 + 22 = 59$

$63 + 31 = 94$
