Question

Another brain exercise :DDD

One day your minimalist friend is visiting, and she presents you with the numbers 2, 3, 4 and 5, and the symbols = and +, and the following tantalizing challenge: It is possible to use each number and symbol once and only once and end up with a true equation; further, you cannot use any number or symbol not given. How can you do this?

Answer 1

I just copied this problem from a website :D this problem is not mine. (i'm avoiding plagiarism)

Answer 2

YOu don't have better things to do? :P

Answer 3

well...this site has so few questions so i thought of entertaining bored people with these :D

Answer 4

i guess, it's impossible.

you have four number's and two symbols,
and one of the number constructed must be two digit number
and smallest two digit number you can have is 23
and the greatest possible number from + operator is 5+4=9

so mathematically, equation is impossible

Answer 5

\[3^2=4+5 \]

Answer 6

oh but it is possible... :D you just need to think outside the box...and fool you cant use symbol not given...there is a hidden ^ symbol in exponents :p

Answer 7

good reply, never considered that possibility, other than that, i guess it's not possible.

Answer 8

Igb, do you have solution other than mine?

Answer 9

@Igbasallote .. but he's not writing any ... has he?

Answer 14

Answer 15

Answer 16

it is a lot easier:
3+4=5+2
:D

Answer 17

no..there's inly one + actually.. 3^2 = 4 + 5 is the only logical answer :D
