You need to use the order of operations PEDMAS
P=Parentheses
E=Exponents
D=Division
M=Multiplying
A=Adding
S=Subtracting
[tex]12(2*3-.5)+10[/tex]
Do whats in the parentheses first and use PEDMAS by multiplying first then subtracting
[tex]12(6-.5)+10[/tex]
[tex]12(5.5)+10[/tex]
[tex]12*5.5=66[/tex]
[tex]66+10=76[/tex]
[tex]Answer=76[/tex]
