99 + 98 = ​

Answer 1

Answer:

99 + 98 = 197

Step-by-step explanation:

It's easy,

See,

We have,

99 + 98

We know that,

99 = 100 - 1

98 = 100 - 2

Add both,

99 + 98 = (100 - 1) + (100 - 2)

= 100 - 1 + 100 - 2

Add the positive terms separately and negative terms separately.

= 100 + 100 - 1 - 2

= 200 - 3

= 197

Hence,

99 + 98 = 197

If that is hard we can do the normal way,

99

+ 98

Adding 8 and 9 gives 17, so write 7 and put 1 carry over.

¹

99

+ 98

7

Now add 9 + 9 which is 18 then add the carry over 1.

So, 18 + 1 = 19

Thus,

99

+ 98

197

Hence,

99 + 98 = 197
