as it may seem, calculators have two major types of logic which change the results you may get from inputting several
The first kind of calculator logic is Serial Logic
That is, the calculator will operate all terms serially.
The arguments 3 + 3 * 5 = will return 45 on a Serial Logic Calculator, because the calculator only handles
two numbers at once. It treats it as such: 3 + 3 equals 9. New Problem, first argument 9. 9 * 5 = 45.
This would be incorrect in algebra
if the problem was "3 + 3 * 5 = x (What is x?)" because that would not follow
The Order of Operations
, which when applied here states that, multiplication
takes place before addition
. Therefore, with a
serial logic calculator
, you must follow the order of operations yourself, multiply
ing 3 * 5 first then adding 3.
On an algebraic logic calculator, imputting the string of arguments 3 + 3 * 5 = will return 18, because the algebraic
calculator treats all numbers as part of the same expression
