Numerals

On an iPad calculator you can enter the numerals 0 - 9 with the keys

 0      1      2      3      4      5      6      7      8      9 

 


Example 1

To calculate 0 × 1 = 0

 0  ×  1  =

and also 0 × 0 = 0

 0  ×  0  =

 


Example 2

To calculate 0 ÷ 1 = 0

 0  ÷  1  =

 


Example 3

Enter 1 ÷ 0

 1  ÷  0  = ERROR 

Dividing by zero always gives a message, and that is correct.

 


Example 4

Enter 00

 0  yx  0  =

That is correct, as it is determined per definition that 00 ≝ 1.

 


Example 5

Enter 0!

 0  x!

This is correct, then it is determined by definition that 0! ≝ 1.

 


Example 6

To calculate cos (0) = 1

 0  cos

 


Example 7

To calculate √0 = 0

 0 

 


Details

In the decimal system you need the 0 to indicate that a place in a decimal number has no value, as in the number 12305. The total value of a number can also be 0.
