Explore basic arithmetic, modulus, incrementers/decrementers. Note string overloads.
- [Instructor] In this video we're going to look at some…simple operators that are used for doing math.…You're not going to need to do a lot of math in the examples…we're going through in this course,…but simple arithmetic comes up pretty often.…The first four operators are pretty simple,…and if you've ever used a calculator program…on a computer, they'll probably look familiar.…We of course have the plus operator.…So, two plus five, that equals seven.…We also have minus, which is technically the hyphen,…so four minus three equals one.…Of course we're not restricted to the counting numbers,…we can do negatives as well, so like,…let's say five minutes nine equals negative four.…
To do multiplication we don't use an X,…we use an asterisk, so, three times five is fifteen.…And then finally we use a slash to do division,…so say 36 divided by six equals six.…And when you start getting into fractions,…the result is expressed using a decimal point.…So these are all fairly straightforward.…Probably nothing you haven't seen before.…
