10−(−2)−3?4−(−4)
First we need to remember the following laws:
We'll solve the left side first.
Let's rewrite the expression in the appropriate form:
Next, we'll solve the exercise from left to right:
Now let's solve the right-hand side, using the laws we reminded ourselves of earlier.
We'll then rewrite the expression in the appropriate form and solve:
Since the left-hand side is larger, the appropriate sign will be:
9 > 8
>
