Answer:
−3−(−7) = 4
Step-by-step explanation:
The given expression is
We know that (-)(-)=(+). So, the given expression can be written as
-3+7
4
We need to find the value of the given expression using a number line.
Two numbers are -3 and -7.
Plot these two numbers on the number line.
Now, start form -7 and jump up to -3 on the number line and count the jumps, then the number of jumps is the answer.
From the below figure it is clear that the number of jumps between -7 and -3 is 4.
Therefore, the value of the given expression is 4.
