Remember the "language of math" and the integer counters. Is there another way to represent 6 - 3?? Surely... how about 6 + (-3). Either way, the "answer" is the same, but the math gods would approach the integer counters in a DIFFERENT WAY.
For 6 - 3, you would start with 6 positives and thenremove 3 positives, leaving you with 3 positives, otherwise known as +3.
For 6 + (-3), you would start with 6 positives, then add 3 negatives, leaving you with a "mish-mash." To clean up the mess, you would then remove 3 zero pairs (a zero pair is a positive and negative counter together) and you are once again left with 3 positives, or +3.
Two different "WAYS" to get the same answer.
Now, can you represent teh problems in #21-24 in a different way than they are stated? It's a tough one, but give it a try!
The hw was the sheet we worked on during class, right? Its labeled Problem Set 2A, which is written as the hw, but at math chamber, it says it is about subtracting fractions...which it wasn't...
This Blog exists for the collective benefit of all algebra students. All questions are welcome. The more specific your question (including your own attempts to answer it) the better.

I do not understand numbers 21-24. whta does it mean two ways?????
