Accepted Solution

A:
Answer:−3−(−7) = 4Step-by-step explanation:The given expression isWe know that (-)(-)=(+). So, the given expression can be written as-3+74We 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.
