25 as 10+10 is 20 plus 5 is 25
25+10+10+10+1+1= 57
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
25 + 15 + 21 + 10 + 11 = 82
10 plus 25 divided by 5 is 15
10+(-25)=(-15)
It is: 25+10+5 = 40
2 and a half plus 2 and a half plus 10 plus 10 = 25

-35
5+5=10 5+5=10 10+10+5=25 so the answer is not 20, it is 25 or 5*5
