Question

(12)+(2)+4?15 (-12)+(-2)+4\text{?}-15

Video Solution

Step-by-Step Solution

Let's solve the equation:

(12)+(2)+4= (-12)+(-2)+4=

We'll locate minus 12 on the axis and move two steps to the left (since minus 2 is less than zero):

-22-21-20-19-18-17-16-15-14-13-12-11-10

We've reached the number minus 14.

Now let's move 4 steps to the right (since 4 is greater than zero):

-22-21-20-19-18-17-16-15-14-13-12-11-10

We've reached the number minus 10.

Therefore, the solution to the equation is:

(12)+(2)+4=10 (-12)+(-2)+4=-10

So the appropriate sign will be:

-10>-15
