Question

What is tha answer to 2-233

Answer 1

2 - 233 = -231
It would be the same as 233 - 2, but negative instead.

Answer 2

A number reduced by a number larger would have a negative sum.

Example:
5 - 15 = -10

An easy way to solve equations like this is to subtract the smaller number from the larger number then add a negative sign to the sum.

Example:
5 - 15 would become 15 - 5
15 - 5 = 10
Just add a negative sign and that is the answer. 
5 - 15 = -10

Now, to solve your equation, we would first reverse the order. 
2 - 233
233 - 2 = 231

Lastly, add the negative sign.
231 would change to -231

Your answer would be -231. 

I hope this helps!
