3-3*6+2= on one calculator it says 2 and on the other it says -13 which is correct if there are NO parenthisis?
+33659 -13 is the correct mathematical result, because multiplication takes priority over addition and subtraction. Scientific calculators should do this correctly.
Some non-scientific calculators just use a left to right priority, so they will do the operations from left to right as they are written. Avoid these left to right calculators like the plague!!
