Best Calculators for Variables

the ability to build algebraic functions around variables and execute them repetitively is also very useful.

one can store formulae in variables f1,- f4, and these may be recalled for rapid analysis of data- such as t-scores and

(this applies to both one and two dimension data.) also, the associated statistics variables (a, b, r, x', y', etc.) are on the keyboard and easily accessible.

it also can prompt you for variable inputs instead of storing the variables before you run the program.

this problem involves 4 separate, inter-related equations to be solved, which use 6 or 7 different table constants and a dozen or more intermediate variables.

-- still only single character variables names.

these equations can be re-executed multiple times with different values for any embedded variables.

you can scroll up + down and change variables as you want.

it has 12 modes, each of which lets you calculate a limited number of variables after the input of another set of variables.

to populate the variables with expression results you must first evaluate and store these before executing the {algb} operation.

it features entry, editing and storage of formulas, has nine variables for temporary storage, supports 4x4 matrices, numerical integration, hex/octal/binary numbers, metric conversions, complex
