Algebraic Substitution
Enter the calculation by replacing each letter in the formula with its corresponding number.
When you have a number of algebraic substitutions to do then it would be easier to use the memory aspect of the
calculator keys. There are 28 different storage places i.e. A ~ Z, θ and Γ. These are accessed via the [ALPHA] key then
the associated key required.
You ‘assign’ a value to the letters you want to use with the [→]
button, then enter the algebraic expression into the calculator. Press
[EXE] for the calculator to store the value in the memory.
