Question

s the value of 3 +(-3) what is the value of (-10.4) + 10.4? these pairs of numbers are called opposites. what is the sum of a number and its opposite?

Answer 1

we have given that
`3+(-3)` and
`(10.4)+(-10.4)`.

we know that a property
`(a)+(-b)=a-b`.

so
`(3)+(-3)` and
`(10.4)+(-10.4)=0`.

these number are called opposites because they have same value but opposite signs.

so the number and opposite of a number is added always equal to 0.
