Question

|6-4|-|3-8|= I don’t understand how it comes out to -3, I amDoing ACT prep and been out of a math class for several years

Answer 1

Given that

There is an equation and we have to solve it.

Explanation -

The given equation is

`\begin{gathered} \lvert{6-4}\rvert-\lvert{3-8}\rvert \\ and\text{ }\lvert{\placeholder{⬚}}\rvert\text{ is the sign of modulus} \end{gathered}`

Since any number inside the modulus is always positive outside the modulus.

Then,

`\begin{gathered} \lvert{6-4}\rvert-\lvert{3-8}\rvert=\lvert{2}\rvert-\lvert{-5}\rvert=2-5=-3 \\ Hence\text{ the answer is -3} \end{gathered}`

Final answer -

Therefore the final answer is -3
