Four-Function Calculators

Four-function calculators are compact, user-friendly devices designed to handle the four basic arithmetic operations: addition, subtraction, multiplication, and division. While they are simple by design, some models go beyond the basics and include additional features such as tax calculation, percentage functions, and memory keys, making them useful in a variety of settings beyond the classroom.

These calculators are ideal for students across all grade levels, particularly in elementary and middle school, where basic math skills are emphasized. However, their utility doesn't stop there. Professionals in fields such as retail, sales, and finance also rely on these calculators for quick and efficient calculations.

Whether you're doing schoolwork or managing quick calculations in the field, a four-function calculator remains a dependable and accessible tool that enhances productivity and confidence in math-related tasks.

Graphing Calculator purchase was wonderful

I am a math teacher in Ogden, Utah. We have ordered from Underwood twice now, buying TI-84 Plus CE graphing calculators both times. They were easy to purchase, a great price compared to others, and arrived quickly. No complaints here! Definitely recommend!

Wonderful source for TI calculator add ons

The Ti 84 launchpad board and RGB led board are hard to find new for just a single user and definitely not at such a good price. Prompt shipping and everything arrived well packed. Seriously great source if you are looking for small quantity at great value. Thanks!

Both Product and Service are excellent.

I search something and they have it, sent an email about it with instant response and Jake helped me order it in a few mins, product arrived much earlier than I expect and in excellent condition.

Best experience!

I ordered a calculator late Monday night that I needed by Wednesday. I communicated with Jake several times via email and once on the phone throughout the next day. Had my calculator before noon on Wednesday. Every response to me was quick, helpful, and very courteous!! Great company and customer service. I will order through them in the future and highly recommend others to do the same.
