Question

let me join you brain teasers: warm-up

Answer 1

I'm guessing you already have the answer.
Is the single digit number either a 2 or 3?

Answer 2

sorry man its hard i can't move forward after a point...:|

Answer 3

is this possible?

Answer 4

i don't think this is possible:
if you have:
aa + bb = cc
cc * d = ee

The lowest possible value for cc is 37 (13 + 24).
This means that d can only be 2 (since 37 * 3 > 100)

Answer 5

yea it isn't possible, I'm almost sure of it

Answer 6

there are only a couple possibilities for it even with 2 as your multiple/d

Answer 7

(and none that work)

Answer 8

yes, because if you use 2 for d, then the lowest possible value for cc is 49 (14 + 35), which isn't possible because that would be using 4 twice
