3-4
If you think about this on a number line, it isn't too hard.
So picture a line with negaitive numbers on the left going to positive numbers on the right. Something like this...
-5 -4 -3 -2 -1 0 1 2 3 4 5
So you want to start and the positive 3 and go to the left 4 numbers...
There's your answer. :]
To solve the equation 3-4, you can use the number line method. Here's how you can do it:
1. Imagine a number line with negative numbers on the left and positive numbers on the right. In this case, it could look like this:
-5 -4 -3 -2 -1 0 1 2 3 4 5
2. Start at the positive 3 on the number line.
3. Moving to the left, count four positions.
4. The number you land on after moving four positions to the left from 3 is -1.
Therefore, the answer to 3-4 is -1.
