Basic integer arithmetic

The common number base used in contemporary mathematics is

base 10. By default, all calculations performed by the HP Prime are

carried out in base 10, and all results are displayed in base 10.

However, the HP Prime enables

you to carry out integer

arithmetic in four bases: decimal

(base 10), binary, (base 2),

octal (base 8), and hexadecimal

(base 16). For example, you

could multiply 4 in base 16 by

71 in base 8 and the answer is

E4 in base 16. This is equivalent in base 10 to multiplying 4 by

57 to get 228.

You indicate that you are about to engage in integer arithmetic

by preceding the number with the pound symbol (#, got by

pressing

Az). You indicate what base to use for the

number by appending the appropriate base marker:

Thus #11b represents 3

. The base marker b indicates that the

number is to interpreted as a binary number: 11

. Likewise #E4h
