1. Example-1
1. Find -3×A
`A=(3,1,1)`
Solution:
Here `vec A=(3,1,1)`
`-3 * vec A`
`=(-3*A_1,-3*A_2,-3*A_3)`
`=(-3*3,-3*1,-3*1)`
`=(-9,-3,-3)`
2. Find 2×B
`B=(-1,2,1)`
Solution:
Here `vec A=(3,1,1),vec B=(-1,2,1),vec C=(3,1,1)`
`2 * vec B`
`=2*(B_1,B_2,B_3)`
`=(2*B_1,2*B_2,2*B_3)`
`=(2*(-1),2*2,2*1)`
`=(-2,4,2)`
