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].
