Module

I recently checked into a Java class and I have a question regarding module splitting.

I'll give an example in my tutorial:

( 100 - 25 * 3 % 4 ) = 97

How does it equal 97? I've tried all sorts of possibilities and I just can't figure it out.

Can anyone be so kind as to break it for me.

Thanks in advance.

Operator priority

( 100 - ((25 * 3) % 4) ) = 97

25*3=75

75 MODULO 4=3



100-3=97

What is it.

When you are unsure of operator precedence, place parentheses everywhere.

The operators *, / and% are called multiplicative operators. They have the same precedence and are syntactically left-associative (they are grouped from left to right).

So whenever there is A op1 B op2 C and both op1 and op2 are *, / or%, which is equivalent

(A op1 B) op2 C



  25 * 3 % 4 -> a * b % c 
  (25*3)%4->(a*b)%c
Operator

(-) is right to the left. operator - Performs evaluation after the expression on the right hand side completes. so the answer is 100- (25 * 3)% 4 = 100-3 = 97
