Additions are generally easy By using some techniques we can make it more easy
1. How do you add 69 and 8?
* you write themon a paper and add right? we can add themmentally and in a easy way. To add 8, first you add 10 and then subtract 2
69 + 10 = 79 subtracting 2 is 77
* It is easy to add 10 than 8
* To add 7, you first add 10 and subtract 3
* If you want to add 46, you add 50 first and subtract 4
For example,
86 + 27
* Here you add 30 to 86 and subtract 3
86 +30 = 116, subtracting 3 is 113
Similarly,
To add 97, you add 100 and subtract 3.
To add 148, add 150 and subtract 2.
To add 189, add 200 and subtract 11
and so on
They really take very less time to add the numbers
Now you try these
1. 37 + 19
2. 84 + 27
3. 125 + 58
4. 257 + 86
5. 735 + 292
