We can calculate the opposite of a number by multiplying it by (-1).
a) The opposite of 6 is 6*(-1)=-6.
b) The opposite of -3 is (-3)*(-1) = 3.
c) "Two numbers 3 away from 1" can be written as:
![2\cdot(3)-1=6-1=5](https://img.qammunity.org/2023/formulas/mathematics/college/ttaz2xx9gg9nndol0ywa5yr8zdgof3vj94.png)
d) A "neither positive or negative" can only be 0.
e) Opposite of 2 is -2.
f) "Two number 6 away from -3" can be written as:
![2(6)-3=12-3=9](https://img.qammunity.org/2023/formulas/mathematics/college/g71i9mnxl071rh531cz3ku8s3t3za3ax4j.png)
