Default Kids Maths Homework

You need to sort out which letter equals which number.....A = 3, F = 5, etc

Is it me or is it an bad question.....i think they have got it wrong (or i'm being dumb!)

This is the q:

D X A = EB
E X A = F
B X A = EC
C X A = A
G X A = EI
F X A = CG
A X A = D
H X A = CH
I X A = CE

Well I & B have the same value.

I'm assuming the are expecting this to be solved as a series of simultaneous equations, and then substitute the knowns in to the other equations and solve accordingly? Is A=3 and F=5 a given or are you giving an example of the answer?

lol...me too! and its for a 9 year old.

if A x A = D then A has to be 2 or 3 ( 4 and above would equal 16 - a double digit number and D is a single digit)

but if A is 2 the D is 4 and the first one (D X A) is 8.....but their answer is EB, a double digit number - same with 3

How do you know I and B have the same value? I presume your looking at the 1 equations

I X A = CE and B X A = EC

the answer is different, if E =5 and C = 4 then

I X A = 45 and
B X A = 54

Shes either got it wrong or they havent explained the question fully, maybe a head start with one of the letters would have helped.... Like what the value of A is.

How old is the kid who has this homework?

I was assuming EC was just the product of E and C rather than the concat. If it's the concat then you are correct, if it's the product then my comment stands, although I did think it a little odd to use the "X" for product on one side and not the other!

but A cant be 1 as that would be A X A = A

it cant be 4 (or above) as A x A = 16 (a double digit number which doesnt tally)

so it can only be 2 or 3 - and that doesnt work!

You can work out what c is, as C*A = A, therefore 1*A = A

C has to be one imo

prob is if C is 1 then B X A = EC is a number ending in 1 (cant be 11, 31, 41, 51 - can only be 21

I know, I was replying to the fact that there has to be a given number (which, effectively, there was)!

Why? maybe EC = 31

value of E being 3 and value of C being 1?

Doesnt say that the numbers add together, they just sit together from my guessing... ?

Didn't I solve this already?
Tiggs, you are answering the puzzle as you are going along now, using the theory that EC = 21, you can then work out that B is 7 etc!
