Use PEMDAS
P= parentheses
E=exponents
M=Multiplication
D=Division
A=addition
S=subtraction
Note: you can do division before multiplication and you can do subtraction before addition
Problem 1: 25-3*3*2
Do multiplication first
3*3 = 9
9*2=18
Then subtract
25-18 = 7
Problem 2: 8+2²*2
Do exponents first
2² Is the same as 2*2
So It's 4
4*2=8
8+8= 16
Problem 3: 12÷1*2-6
12÷1=12
12*2=24
24-6=
18
Problem 4: 12÷(1*2)-6
Do parentheses first
1*2=2
12÷2=6
6-6=0
Problem 5: 5-2⁴÷2³*2
5-16÷8*2
5-2*2
5-4
1
Problem 6:
(5-2⁴÷2³)*2
(5-16÷8)*2
(5-2)*2
3*2
6
Hope this helped
