Answer :
Certainly! Let's solve these questions step-by-step.
### Question 6: Subtract -77 from the sum of -7 and -70
1. Start by calculating the sum of -7 and -70:
[tex]\[ -7 + (-70) \][/tex]
This equals:
[tex]\[ -77 \][/tex]
2. Next, subtract -77 from the sum obtained in step 1:
[tex]\[ -77 - (-77) \][/tex]
Remember that subtracting a negative number is equivalent to adding its positive counterpart:
[tex]\[ -77 + 77 = 0 \][/tex]
So, the result is:
[tex]\[ 0 \][/tex]
### Question 7: Subtract the sum of 1320 and -2020 from -809
1. Start by calculating the sum of 1320 and -2020:
[tex]\[ 1320 + (-2020) \][/tex]
This equals:
[tex]\[ -700 \][/tex]
2. Next, subtract the sum obtained in step 1 from -809:
[tex]\[ -809 - (-700) \][/tex]
Again, subtracting a negative number is equivalent to adding its positive counterpart:
[tex]\[ -809 + 700 = -109 \][/tex]
So, the result is:
[tex]\[ -109 \][/tex]
### Summary of Results
- From Question 6, the result is [tex]\(0\)[/tex].
- From Question 7, the result is [tex]\(-109\)[/tex].
