Answer:
1. 0.5
2. 64
Step-by-step explanation:
1. (11 +33 - 42 ) ÷ ( 8 - 4 )
Order of operation is PEMDAS
Parenthesis , exponents, multiply or divide, addition or subtraction
First we start with parenthesis
1. (11 +33 - 42 ) ÷ ( 8 - 4 )
Simplify the parenthesis
so its 2÷ 4
answer is 0.5
2. (10 - 2 )^2 + ( 5 - 10 ÷ 2 )
First simplify the parenthesis
(8) ^2 + (5 - 10 ÷ 2)
Inside the parenthesis we have subtraction and division
As per order of operation we do the division firs and then subtract
(8) ^2 + (5 - 5)
(8) ^2 + 0
now we do the exponent 8^2 is 8* 8
64 + 0
64
