@101altair That would work here but more most of these it wouldn't. It only works here because a does happen to be equal to 0 while other times it may not.

Idk if this was said but to me that made no sense. So how about we use common sense and just multiply the 24 by 2 and add that to 0.... When you have like 20 minutes to do 20 problems wouldn't a quicker way be recommended???

Just had dinner? 7:48 LOLOL

[101altair]

can this also work? since 1x is 24, 2x would be 48, and 0x would be 0, so a+b would be 48+0 which equals 48, the answer, would you reccomend this technique?
