Trent Die-hard

working on this last night. It took my longer than it should have because I kept trying solutions with only two numbers in the parentheses.

It was funny seeing the problem on CB this morning knowing how we struggled with it last night.

Math Question: using only the following numbers and symbols, write an expression

BYU-Ite

Do you have to use all of them?

TwinsRight

9/23/22 7:53am

Yes.

BYU-Ite

9/23/22 7:54am

exponent of 3?

Baron

9/23/22 7:54am

Yes. Meaning you have to have either 1^3 or 2^3 or 3^3

BYU-Ite

9/23/22 7:55am

If you don’t have to use them all, then 2 exponent of 3 = 8

Except you have to use the + and - and (). This is my daughter’s sixth grade

(3-2+1)^3 = 8

Dang it! I shouldn't have spent so long double checking my math 🤔😉😅

Freak!! That’s it! You da man! I couldn’t get that forever. Thank you!!

Being an actuary has its perks. Didn’t think it’d be CB math problems but alas

Cougs2012

9/23/22 7:59am

I kept thinking, “this shouldn’t be that hard….” And apparently it wasn’t. Guess

Haha it helps when you do math for a living, everyday!

The exponent of 3 is a giveaway that the solution will have to devolve to 2^3 at

yeah, I worked backward from that point as well.

I prefer (3+1-2)^3

Don’t know why I thought you said equal to zero, nothing to see here

(3+1-2)^3=8. Thanks. That was a fun 30 seconds...on to nerdle

(3+1-2)^3

Alternative answer that doesn't cube the 2 — (3^3)-2+1=8

unctoothman

9/23/22 8:11am

3^3 would be 27

PHXSUNS31

9/23/22 8:19am

Right. So 27, then take away the 2 (i.e. make 27 into 7) then add 1. Equals 8. Easy.

unctoothman

9/23/22 8:39am

Genius

PHXSUNS31

9/23/22 8:56am

But it's supposed to be a math expression, not a meth expression.
