Answer 10

have u got it how to solve it ?

Answer 11

BODMAS
\[[(3+5) \times 2-5] \times 3\]
start with the first bracket (3+5)
[8 x 2 - 5] x 3
Now the main bracket. Start with multiplcation
[16-5] x 3
Before you multiply make sure you have solved everything in the bracket
[16-5] x 3
11 x 3
33

Answer 16

You gotta follow me though:)!! Here we go:)
[(3 + 5) • 2 – 5] • 3
Add the parentheses first:)
[8*2-5] *3 Next multiply 8 and 2
