Step-by-step explanation:
You are just replacing the 'n' with the number in the 'n box'.
So if this is the formula:

then:
B(-3)= 4-(-3/3)
B(-3)= 4-( -1)
B(-3)= 4+1
B(-3)= 5
B(0)= 4-(0/3)
B(0)= 4-0
B(0)= 4
B(3)= 4-(3/3)
B(3)= 4-1
B(3)= 3
Answer: FAT SONIC SAYS.... THE ANSWER IS 125
So order of operations
4-3+12
now we solve left to right
1+12=13
13
:)
45 over 48 because 3 over 8 times 1 over 6 equals 3 over 48 and 48 take away 3 equals 45
