This has been asked before but we need to know HOW to get to the right answer please.

I have no idea what the answer is…

So, do we assume that you already know what the answer is? In fact, there is only one possible answer.

SHHH has four digits, and ZZZ only three. So you add a single-digit number to ZZZ and get a 4-digit number.

There are only 9 3-digit numbers of the form ZZZ, so try them all out : 111, 222, 333, and so on. Do any of them give you a 4-digit result when you add on a single digit number ?

I think that you will find there is only one such number. And this will tell you what digit S must be, at the front of SHHH. Whatever single digit you add on to ZZZ, there is only one number which the S at the front of SHHH can possibly be. So that is the digit which you must add on to ZZZ.

That, I think, answers your question, HOW you get the right answer.

Im using a cheap method to get this

S = any number pick one

H = 1

Z = 0

9*1*1*1 = 9

9-9 = 0

0*0*0 = 0

im sure they want you to use a number other than zero but if they dont put that down your teacher will give u an A for effort but u might get it wrong
