Year 12s: what will be the first way you research your future options? >>

computer science, please a quick help guys

Calculate the following :
Exercise 3.1
695 % 20
7 + 6 * 5
248 % 100 / 5
6 + (18 % (17 - 12))

Exercise 3.2
(1 + 2) * 3 + 4 =
24 / 2 * 4 =
5 + 4 % 7 / 2 =
5 + 4 % (7 / 2) =

Exercise 3.3
Integer z, y=-3
z= 8 – (3 + 7 / 2) + 3 * - y

Exercise 3.4
Given integer variables a, b, c, d, and e, where a = 1, b = 2, c = 3, d = 4,
evaluate the following expressions:
1 + a * b % c
a + d % b - c
e = d + c / b - a

This isn't even computer science, this is basic arithmetic. What are you struggling to understand?

You can't come up "with a diff answer" every time because the rules for operator priority are well defined so there is only a single answer.

This isn't a homework service so people aren't going to give you the answers - why not post a couple of your results and someone can check them for you? :smile:
