15 - 1 = ?

• math - cassandra, Tuesday, April 26, 2011 at 9:57pm

14 positive

• math - cassandra, Tuesday, April 26, 2011 at 9:57pm

when adding a negative with a positive the answer isn't always negative?

• math - Ms. Sue, Tuesday, April 26, 2011 at 10:02pm

No. When adding and subtracting, the sign depends upon the numbers.

When multiplying and dividing a negative and a positive, the answer is negative.

Right.

Right.
