Question

Given the vectors, a=3i+4j, b=-2i+5j, c=10i-j, d=-1/3i + 5/2j, find a+(b-c)=?

Answer 1

a +(b -c) = -9i +10j

Explanation:

You can use the distributive property to remove the parentheses:

a +(b -c) = a + b - c

Add the vectors as though they were binomials.

a + b - c = (3 -2 -10)i +(4 +5 -(-1))j = -9i +10j
