Why do we need to memorize formulas?
The second big reason for memorizing formulas is that when you have an equation immediately accessible to you, you will start to see connections much faster between material you’ve already learned and material you’re encountering for the first time, and the toolbox you have for working with unknown concepts will be …
Do they give formulas on PSAT?
Formulas are provided to test-takers so that they may focus on the application, rather than the memorization, of formulas. However, the test does not provide a list of all the basic formulas that will be required to know for the test. This means that you will need to be able to recall many math formulas on the PSAT.

How do you use multiple references in a formula?
You can use multiple references to other sheets in the same formula. To use an already created reference, you can type or copy the name of the reference—surrounded by {curly braces}—into a new formula. References are unique to the sheet they’re created on and can’t be used on other sheets without recreating them.
How do I create a sheet reference for a formula?
When you’re creating a long formula, you may need to refer to a cell or a range in another sheet, and then have a need to come back to the origin sheet and refer to some cell/range there. When you do this, you will notice that Excel automatically inserts a sheet reference to the sheet where you have the formula.
Which functions don’t support references from another sheet?
The following functions don’t support references from another sheet: CHILDREN, PARENT, ANCESTORS. Using a reference from another sheet with these functions will result in an #UNSUPPORTED CROSS-SHEET FORMULA error in the cell containing the formula. For more information on this and other formula errors, see Formula Error Messages.
How do you write a formula that refers to another worksheet?
When writing a formula that refers to cells in another worksheet, you can of course type that other sheet name followed by an exclamation point and a cell reference manually, but this would be a slow and error-prone way.
