Find the number below 50, a multiple of 4 the sum of its didgits is 5
a 2 - digit number a multiple of 7 the product of it's digits is 16
a square number below 50, the sum of its digits is 9

I was hoping someone can explain these to me

This is all i got to.

We have a two-digit number, the sum of its digits is 5.

There are only five such numbers: .\begin{Bmatrix}14 \\ 23 \\ 32 \\ 41 \\ 50 \end{Bmatrix}

Only one is a multiple of 4: .32

Sounds like a maths tongue twister.

Dare someone to use calculus (somehow) to solve this. GOGOGOGO

As for how to solve it, just guess. Trust me, it's MUCH faster than using algebra to solve them. I generally started with the second clue and worked out all the possible combinations, and checked them against the second clue.
