"You won't always have a calculator in your pocket" teachers used to say. Yeahhh...awkward. So, yeah, most of us now have calculators with us at all times, which might help you avoid overpaying for a meal, especially when your friend orders a tonne of sides (read the room, dude, it's only brunch!). This site is more than just a calculator; it's the best problem-solving resource for students, parents, and teachers (thank goodness). They aid in the completion of more difficult arithmetic activities such as Algebra, Trigonometry, and others.
