Simple ExerciseGo to you windows calculator and make sure it is in standard view.
Type 1 + 2 * 3 =
You will get 9!
Switch to scientific view and repeat the same i.e.
1 + 2 * 3
You will 7!
Reason:The non-scientific calculator expects two operands and an operator. When the next operator is pressed, the expression is immediately evaluated and the answer becomes the left hand of the next operator. Advanced calculators allow entry of the whole expression, grouped as necessary, and only evaluates when the user uses the equals sign.
Moral of the Story:Some of us are in scientific view while others are in
standard view.
Recommendation [And this is VERY serious]:Some people should not be allowed to help their kids with homework. Otherwise we will end up with rich dad, poor son!!!
