口 - 6+2+1+10+10+10+10+2+10

49

Step-by-step explanation:

- 6+2+1+10+10+10+10+2+10

so lets add from the start . . .

-6+2=-4

-4+1+10+10+10+10+2+10

then slowly work your way through the problem

-4+1=-3

-3+10+10+10+10+2+10

-3+10=7

7+10+10+10+2+10

you could do it the standard way of 7+10+10+10+2+10

but since there are 4 tens left . . . you can do 7+2+ 10(4)

9+40

answer is 49
