help with my daughters 3rd grade math?

This is embarrassing but I'm having trouble helping my 3rd grade daughter do her math homework. I'm really stuck. It says to write an expression AND a number sentence for the problems. The problem is Martha had 10 rocks and gave 4 to a friend. How many does she have left? Well the number...

It's kind of weird they are asking for that since an expression is just an equation (with an equal sign) without an equal sign. At least in my eigth grade algebra math an expression would be 10-6

And yeah haha best of luck!

Mine is in Grade 10 and I'm sitting here doing the same thing.

I think yours would be

10-4=x

6=x

and I do remember them having to write out answers to problems in words as well.

Martha has 6 rocks left.

Am I sure?...no.

They are saying that if you have 10 and you subtract 4 then you get 6 lest over so 10 - 4 =6

Tn+1 = Tn-4 , T1 = 10

Therefore T2 = 6

The expression doesn't have to be in English!

"10 - 4" is what I would put on the line.

10 - 4 = 6 is technically an equation, since it has an equals sign. It's kinda like clauses in grammar...

an expression is using a letter to mean an unknown number

in this case

10 - 4 = X

I think it may be : 10 is decreased by 4 to give the sum 6

I'm pretty sure it just means writing "ten minus four is equal to six"
