Answer :
Sure, let's break down the solution step-by-step.
### Step 1: Calculate the sum of 42 and -6
[tex]\[ 42 + (-6) = 42 - 6 = 36 \][/tex]
### Step 2: Calculate the sum of -42 and 6
[tex]\[ -42 + 6 = -42 + 6 = -36 \][/tex]
### Step 3: Subtract the sum from Step 1 from the sum from Step 2
[tex]\[ -36 - 36 = -36 - 36 = -72 \][/tex]
### Step 4: Calculate the sum of -7 and -70
[tex]\[ -7 + (-70) = -7 - 70 = -77 \][/tex]
### Step 5: Subtract -77 from the sum in Step 4
[tex]\[ -77 - (-77) = -77 + 77 = 0 \][/tex]
So, the detailed step-by-step results are as follows:
1. Sum of 42 and -6 is 36.
2. Sum of -42 and 6 is -36.
3. Subtracting the sum in Step 1 from the sum in Step 2 gives -72.
4. Sum of -7 and -70 is -77.
5. Subtracting -77 from the sum in Step 4 gives 0.
### Step 1: Calculate the sum of 42 and -6
[tex]\[ 42 + (-6) = 42 - 6 = 36 \][/tex]
### Step 2: Calculate the sum of -42 and 6
[tex]\[ -42 + 6 = -42 + 6 = -36 \][/tex]
### Step 3: Subtract the sum from Step 1 from the sum from Step 2
[tex]\[ -36 - 36 = -36 - 36 = -72 \][/tex]
### Step 4: Calculate the sum of -7 and -70

So, the detailed step-by-step results are as follows:
1. Sum of 42 and -6 is 36.
2. Sum of -42 and 6 is -36.
3. Subtracting the sum in Step 1 from the sum in Step 2 gives -72.
4. Sum of -7 and -70 is -77.
5. Subtracting -77 from the sum in Step 4 gives 0.
