# LET

Formulas / LET
Assign variables in a formula.
`=LET(name1, name_value1, calculation_or_name2, [name_value2, calculation_or_name3...])`
• name1 - required argument that is the first name to assign
• name_value1 - required argument that is the value assigned to name1
• calculation_or_name2 - required argument that is a calculation that uses all the names in the LET function
• name_value2 - [OPTIONAL] argument that is the value assigned to calculation_or_name2
• calculation_or_name3 - [OPTIONAL] argument that is a calculation that uses all the names in the LET function
• name_value3 - [OPTIONAL] argument that is the value assigned to name_value2
• calculation_or_name4 - required argument

## Examples

• `=LET(x,10,x+1)`

The LET function can be used to assign a value to a variable, and use the variable in a calculation. In the example, the LET function assigns the value 10 to the variable "x", and then adds 1 to the value of "x". This expression returns the value 11.

• `=LET(x,10,y,5,x+y)`

The LET function can also be used for more complex calculations that involve multiple variables. For example, this formula assigns the value 10 to the variable "x" and the value 5 to the variable "y", and then adds the two values together. This expression returns the value 15.

## Summary

The LET function is a useful tool for defining and creating named variables in a formula. It helps to simplify and organize data in a formula.

• The LET function reduces redundant calculations to improve performance and makes complex formulas easier to read and write.
• The LET function is often used with LAMBDA to make a complex formula easier to understand.

What is the LET function?
The LET function is a formula tool in spreadsheet programs that assigns names to calculations and values. It allows users to assign names to calculations and values directly in a formula, making formulas more readable and easier to understand.
What are the benefits of using the LET function?
Using the LET function allows for easier readability of complex formulas, as it assigns names to calculations and values directly in the formula. This makes it simpler to understand the formula and the components that make it up.
What calculations and values can I assign names to using the LET function?
The LET function allows you to assign names to calculations and values directly in a formula. This includes any type of calculation or value that you can use in a spreadsheet formula, such as adding, subtracting, multiplying, dividing, and more.
How do I use the LET function?
To use the LET function, you must first assign names to the calculations and values you wish to use. This can be done by adding a label to the calculation or value. After this is done, you can then use the LET function in your formula by placing the assigned name within a pair of parentheses.
