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:

Base marker	Base
[blank]	Adopt the default base (see
	“The default base” on
	page 582)
d	decimal
b	binary
o	octal
h	hexadecimal

Thus #11b represents 310. The base marker b indicates that the number is to interpreted as a binary number: 112. Likewise #E4h
