i have an example

=27x10
=270÷2
=135
by halving it and then halving it again
yes
no, dividing a number is halving it, multiplying iy by 2 is doubling it
The opposite of double is "half." While doubling a number means to multiply it by two, halving a number means to divide it by two. Essentially, doubling increases a quantity, whereas halving reduces it to half its original value.
Halving in math or anywhere else is cutting things in half, dividing by two.

i need this answer
Trying to make a number repeating (75 + 78 = 75+75+3)
Doubling a number means multiplying it by 2. This is equivalent to adding the number to itself. Halving means dividing by 2. This is equivalent to multiplying by 1/2 (or by 0.5); since this is not an integer, it can't be reduced to addition.
Squaring for multiplying, and if you are dividing by the same number, you get 1
It is exponential. +3 decibels is a doubling of power in watts, while -3 decibels is a halving of power in watts.
