The memory feature lets you store a number. A number you want to use later.

To set the memory to 2, we make  m = 2.

Enter:

2

You can set m to be the result of an expression.

For example:

1.2 ÷ 3.4

If you like, you can do it like this:

1.2 ÷ 3.4

Let’s use m in an expression:

100 ×

Sometimes you forget the value of m, to find out,
enter and press return.

It’s no surprise that memory is like a variable.

From the above example, with m = 0.3529411764

100 × m = 35.29411764

Let’s look at our History:

Let’s set  m = 2.

Notice the result is updated, instantly.

This technique is useful for repeating the same calculation with different numbers.

If you have configured the key  =  as+
in Preferences > Shortcuts:

You may be wondering how to get    via the keyboard.

You can either:

• Press shift-equal:  =
• Or press equal twice:   ==

Actually ‘m’ is just one of the memories;
you can use a, b, m, or n, anytime and anywhere.

If that’s not enough, you also have the secondary
a2, b2, m2, and n2. Here’s how to access them.

## Via the mouse:

Hold down the memory button until its menu appears.
(You can also right-click or control-click.)

## Via the keyboard:

Press M for m. For m2 press M twice.

Mm

MMm2

In other words, you press same key twice for the secondary memory:

Aa

AAa2

And to set b2 = 20, you enter:

20
