Please someone can help me with this problems. Thanks

Answer 1

How about the last one.
\[[[(8-3) \cdot 2]+[(5\cdot 6)-5]] \div 5\]
First step: Perform operations inside grouping symbols
Second: Take care of exponents
Third: Mult/div as it occurs left to right
fourth: Add/sub as it occurs left to right

Answer 2

So [ ] and ( ) are grouping symbols

Answer 3

so the first [ ] I see is that very very large one
let's go inside it
I see two of these now [ ] inside
let's look at the first [ ]
we have (8-3)*2

Answer 4

( ) is a grouping symbol
perform the operation inside there first

Answer 5

(8-3)*2
what is 8-3?
