The difference between -10 and 7 is 17
1Step 1: Problem Formulation
Consider the problem of finding the difference between -10 and 7.
2Step 2: Identify the Numbers
There are two numbers to consider here: -10 and 7.
3Step 3: Apply the Rule
Next, apply the rule of subtraction. Subtracting a number is the same as adding its negative. Thus, subtracting -10 (negative number) is same as adding 10 (its positive).
