Method 1:
Count 13 more numbers after 13. But this method is suitable for only small numbers.
Method 2:
Steps of addition of two or more numbers:
1 - Add the digits of ones place and if the result is greater than 10 then then only 0 is written and 1 is taken as carry to the tens place. If result is less than 10 then the number is written.
2 - Then we add the digits of tens place with carry if there is any and the same procedure is to be followed mentioned in the first step.
Here the digit 3 is at ones place and 1 is at tens place in both numbers.
Addition of 3 and 3 = 6
Addition of 1 and 1 = 2
The corresponding digits which we get on addition are written in the corresponding places.
6 takes its place at ones place and 2 at tens place.
The result so obtained is: 26.
13
-13
13+13+13+13+13+13+13+13+13+13 = 13 * 10 = 130.
91
13 plus 13 is equal to 26
Plus 12 plus -13 plus plus 1 can be rewritten in mathematical terms as: 12+(-13)+1 or 12-13+1 12-13+1 =-1+1 =0
It is: 5+13+18 = 36
17x + 13
(13+5)18=13+(5+18)
13 x 3 JHC!
If: x+0 = 13 then x = 13
= 18x + 13
