The Excel Syntax:

Every Excel formula begins with an equal sign (=), signaling Excel to perform a calculation. You input the formula's elements, including numbers, cell references, operators, and functions.

• Operators: These symbols specify the calculation you want to perform. Examples include addition (+), subtraction (-), multiplication (*), and division (/).
• Equal sign: Before you create any excel formula or function, you must start with the equal sign (=) in the cell where you want the result to appear.
• Addition: to add values of two or more cells. Example =C5+D8
• Subtraction: to subtract values of two or more cells. Example =D8-C5
• Multiplication: to multiply the values of two or more cells. Examples =C5*D8
• Division: to divide the values of two or more cells. Examples =D8/D5

Putting all this together, you can create an Excel formula that adds, subtracts, multiplies and divides in one cell. Example = (C5+D8)/((D8-C5)*3)

• Functions: Excel boasts a vast library of built-in functions that organize, manipulate, and manage data in spreadsheets, such as SUM, AVERAGE, VLOOKUP, and more, each designed for specific calculations.
• Cell References: Instead of typing in numbers directly, you can refer to the cells in the Excel spreadsheet where the data is stored. This makes your Excel formulas and functions dynamic, as they automatically update when the cell contents change.

Why It Matters:

Understanding the syntax and structure of Excel formulas is crucial for anyone looking to make the most out of this powerful tool. It's not just about performing calculations; it's about streamlining your workflow, enhancing productivity, and making informed decisions based on data.

Once you understand the syntax, every other Excel formula, calculation, and function becomes easy to understand and use. 

For more complex formulas, you’ll need use the parenthesis around the expressions to avoid accidentally using the PEDMAS order of operations.
