How to use excel multiplication formula

Excel multiplication formula usage: Simple multiplication: use the asterisk (), for example =A1B1 Array multiplication: use the MMULT function, for example =MMULT(A1:A5, B1:B5) Matrix multiplication: use the PRODUCTSUM function, for example =PRODUCTSUM(A1:D3, E1:H3)

Excel multiplication formula usage

Simple multiplication

For simple multiplication, you can use the asterisk (*). For example, to multiply the value in cell A1 by the value in cell B1, use the following formula:

<code>=A1*B1</code>

Array Multiplication

To multiply two arrays, you can Use the MMULT function. This function returns an array that is the result of multiplying corresponding elements of two arrays. For example, to multiply the range of A1:A5 by the range of B1:B5, use the following formula:

<code>=MMULT(A1:A5, B1:B5)</code>

Matrix Multiplication

To multiply two matrices , you can use the PRODUCTSUM function. This function returns the sum of the multiplication of corresponding elements of the matrix. For example, to multiply the matrix of A1:D3 by the matrix of E1:H3, use the following formula:

<code>=PRODUCTSUM(A1:D3, E1:H3)</code>

Notes

• Multiplication Operator ( *) has higher precedence than the sum operator ( ).
• For large arrays or matrices, multiplication operations can be time-consuming.
• Check whether the cell reference is correct to avoid errors.
• Learning about functions in Excel can help you perform complex operations, including multiplication.
