Number crunchers come in the form of many devices, apps and gadgets. The evolution became very rapid in the past few decades, considering that before then humans used the abacus and other simple mathematical tools for centuries before.

Now this device almost comes standard as a side feature on phones, computers and sometimes even watches. They are handy tools that often are taken for granted after school is completed, unless of course one's field is mathematically based.

Calculators may not be purchased as a stand alone as often anymore, but they still offer more style and creativity than ever. They come in retro-inspired looks, sleek designs and appealing styles.

Number crunchers do more than just solve math problems, they help humanity evolve in everyday life.
