Which computer is used for number crunching?
(1) A computer whose dominant characteristic is its ability to perform large amounts of numerical computations quickly. Supercomputers, for example, are sometimes called number crunchers. In addition, the term number cruncher is often applied to powerful workstations.
How do you do number crunching?
One way to do this is to put the machine into reverse. This reverse machine first works out 15 – 3 = 12 and then divides 12 by the covered machine number to get 4. So 12 ÷ = 4, giving = 3. The students can try different machine numbers to see which ones work.

- Give equivalents. Help the reader or listener visualize the number with equivalents, especially when giving measurements.
- Check the math.
- Beware Percentages.
- Approximations and rounding.

Kenbak-1. The Kenbak-1, released in early 1971, is considered by the Computer History Museum to be the world’s first personal computer. It was designed and invented by John Blankenbaker of Kenbak Corporation in 1970, and was first sold in early 1971.
How does the number crunching machine work?
If a positive integer is fed into the number crunching machine, it produces one of two results: If the integer fed in is EVEN, the machine divides the number by 2. If the integer fed in is ODD, the machine subtracts one from the number. If a negative integer is fed into the number crunching machine, it produces its additive inverse.
How can I become good at number crunching?
Number crunching operations are generally just basic addition, subtraction, multiplication, and division. Assuming you already know how to do basic arithmetic, becoming good at number crunching is a simple matter of practice. For very large numbers, it helps to use a pen/pencil and paper. Trying do do calculations mentally can speed up both written
