What is -3 squared? |
2014-11-12 |
|
From Christine:
On a math test, it said "What is -3 squared?" It did NOT say "What's is (-3)squared"
The teacher's explanation is that if there are no brackets or parenthesis, you ALWAYS square the number first then do the negative, so the answer should be -9, but I can't find anywhere that confirms this.
Help please.
