How to Use Memory Buttons on Calculator:


We have all seen them, on desktop and mobile calculators: the memory buttons that scientists typically use to store numbers as a form of quick reference. In this post, we show how Memory Buttons work, how to create them, and how they can improve learning.


When describing how to use various calculator functions, this guide gives the exact keys that you need to press using the symbols shown on the keys. This is known as a ‘key sequence’. If the key sequence accesses the second function of a key, or a function from a menu, the name of this function will be given in brackets at the appropriate point in the key sequence. Names in brackets are thus not keys that you press but simply describe the function that is accessed using the previous key sequence. For example, to turn off the calculator, press.Enter numbers either by clicking on the buttons or using the keyboard (note: to use a numeric keypad make sure Num Lock is on). To enter a number in exponential format, enter the mantissa, followed by the EXP key, then +/- if required, then the exponent. To use the arithmetic functions, click their buttons. If the function is unary (i.e. acts on one number, e.g. 1/x) the display is updated to the result. If the function is binary (e.g. +, -, X etc.) enter the second number and click = or another arithmetic key.

As part of your UCAT preparation it is worth taking some time to brush up on your mental maths. For example, learning up to your 20 times table could prove to be incredibly helpful on test day as once again, knowing that 15 x 17 is 255 could save you ten seconds of time by not having to input this into the calculator. Don’t underestimate how long this would take using a keyboard and mouse!Input a value to one of ten memories (labelled 0-9) using this button, which is obtained by pressing the shift button. After pressing MnIn press the number button corresponding to the desired memory. Memory number zero is the default memory (i.e. the memory referred to by the un-shifted memory buttons). The "Clear All" button allows you to delete the contents of all the memories. (Source: www.calculator.org)
