It is: 10+5 = 15
8/10 + 5/10 = 13/10
50 put it like this 20 plus 20 is 40 than 5 plus 5 is 10 then whats 40 plus 10 which is 50 if you dont understand that 20 plus 5 is 25
10 + 10 + 10 + 5 + 5 +1 = 41.
One method is (10×4)+(5×3) = 55 (or mentally add up from left to right).
The sum of 30 plus 10 plus 5 plus 5 is 50.
5+5=10 5+5=10 10+10+5=25 so the answer is not 20, it is 25 or 5*5
25 as 10+10 is 20 plus 5 is 25
5x4=10
