Little Johnny was trying to work out a Maths Magic problem his teacher had given him at school that day. He was having problems, so he asked his mom to help.
The problem read, MAD + AS + A = BULL
“Mom”, he said, “I need to use some of the numbers from 0-9 to work out this problem. I have already figured out from Skippy at school that D equals 3 and L equals 7, but I can’t get the rest. Each letter stands for only one number.”
His mother helped him figureb out the answer.

Answer
983 + 86 + 8 = 1077 is the answer, based on what Johnny knew at the beginning.
