Answer:
< 4, - 7 >
Step-by-step explanation:
- w - z
= - < - 5, 3 > - < 1, 4 > ← multiply each component in w by - 1
= < 5, - 3 > - < 1, 4 > ← subtract corresponding components
= < 5 - 1, - 3 - 4 >
= < 4, - 7 >
Multiplication was invented to reduce the work involved in repeated addition.
... 88 + 88 + 88 + 88 = 4×88 = 352
