Question

Which operation should you perform first when you simplify `63-(2+54*6)-:5`?

Answer 1

First operation is the calculation within the brackets.

Explanation:

Checking the formatting of the question in edit mode shows that within the brackets we have `(2+54xx6)` and not `(2+54.6)` as I first assumed.
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Given:`" "63-(2+54xx6)-:5`

Brackets first:

Within the brackets

Multiply before add `->color(brown)((2+54xx6))color(blue)(->(2+324))`

`color(brown)(63-(2+324)-:5)" "color(blue)(->" "63-326-:5`

Multiply/divide before add/subtract

`color(brown)(63-326-:5)color(blue)(" "->" "63-65.2`

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`"So "color(brown)(63-(2+54xx6)-:5color(blue)( = -2.2)`
