Why is the answer to ((8+4)/2) 6.0 and not 6.

Answer 1

TIREHEAD ,
you have not mentioned the programming language you are using. assuming it is python:
▪︎all results from a division in python are float numbers. so the result is 6.0

Answer 2

The answer of 6.0 would depend on the programming language for used. In most the result would actually be an int, when / is used, truncating the fractional portion. I'm guessing that you're using Python, since this seems to be the course you're doing. In Python the use of the / operator will result in a floating point number and the // operator will result in floor division or integer division.

Answer 3

TIREHEAD
In python you will always get output in decimal because normal division (/) returns value with fraction part.
If you don't want like that then use floor division (//)
(8 + 4) // 2 #gives 6
(8 + 4) / 2 # gives 6.0
floor division returns without fraction part.
