Question
Add the following:
7abc, -5abc, 9abc, -8abc
7abc, -5abc, 9abc, -8abc
✓
Answer
Adding the given terms,
We have,
7abc + (-5abc) + (9abc) + (-8abc)
= 7abc - 5abc + 9abc - 8abc
= (7 - 5 + 9 - 8)abc
= (16 - 13)abc
= 3abc
We have,
7abc + (-5abc) + (9abc) + (-8abc)
= 7abc - 5abc + 9abc - 8abc
= (7 - 5 + 9 - 8)abc
= (16 - 13)abc
= 3abc
