I'm sure you did Andrew thank you
You're quite welcome. Always glad to be of help. Now, in what sense is this a "riddle"?
Could also be:
3+3+3x3 = 15
5x5x0 = 0
Very good, bermbits. Very good, indeed. The devil's in the notation.
thirty - six minus ten = 34
thirty - six minus ten = 34
six minus ten is negative 4. 30 minus neg 4 is 34.
Not so easy, Don!
Some hateful math teacher pounded in my head 30+ years ago, that if no parentheses are used, all division and multiplication should happen before any addition or subtraction. So I think markr has the answers right.
Stumble It!
