Answer 2

That's correct! You've correctly simplified the expression step by step.

Starting with the original expression:

900 - 7

You can break it down as follows:

1. (890 + 10) - 7: First, you simplify the addition within the parentheses.

2. 890 + (10 - 7): Then, you simplify the subtraction within the parentheses.

In both cases, you end up with the same result:

900 - 7 = 890 + 3 = 893
