Ditch the Calculator: Why and How to Use Excel for All Your Calculations

I haven't touched a calculator in ages. Why? Because Microsoft Excel handles all my calculations with ease, and it can do the same for you.

Why Excel Trumps a Calculator

While a calculator remains essential for those working primarily offline (engineers, scientists, etc.), desk-based work flows far smoother with Excel. Here's why:

• Digital Workspace: Your calculations are saved, organized, and accessible, unlike fleeting calculator entries.
• Ergonomic Advantage: Larger keyboard keys minimize accidental keystrokes.
• Advanced Capabilities: Excel performs complex calculations, such as date differences, that calculators can't.
• Effortless Repetition: Easily repeat calculations via copy-paste, saving time on complex formulas.
• Transparent Process: Review and debug calculations by examining the formula bar.
• Data Visualization: Transform simple calculations into professional worksheets with tables and charts.

Mastering Excel as Your Calculation Engine

All Excel calculations begin with an equals sign (=). Let's explore different calculation types:

Basic Arithmetic

Excel performs standard arithmetic just like a calculator. For instance:

<code>=4+5+10 </code>

results in 19 (displayed in the cell, with the formula visible in the formula bar). The same applies to addition ( ), subtraction (-), multiplication (*), and division (/). Negative numbers are handled by preceding the number with a minus sign (-).

Excel follows the standard order of operations (PEMDAS/BODMAS), with additional operators for its advanced functions. Parentheses control the order of operations. For example:

<code>=(20*2)+(6/3)</code>

yields 42.

Cell References

Instead of numbers, use cell references. To multiply A1 by B1:

<code>=A1*B1</code>

Excel's AutoSum simplifies calculations. To average column A values, select the cell below the last value, click the "AutoSum" dropdown in the Home tab, and choose "Average." This works for columns and rows.

Advanced Calculations

Excel handles complex calculations beyond AutoSum. Access more functions via "More Functions" or use these manual inputs:

Calculation	Formula	Example
Square Root	=SQRT(x)	=SQRT(16) returns 4
nth Root	=x^(1/n)	=512^(1/3) returns 8
Square	=x^2	=4^2 returns 16
Exponentiation	=x^y	=5^3 returns 125
Pi	=PI()	=PI()*2 returns 6.283...
Absolute Value	=ABS(x)	=ABS(-5) returns 5

Excel also provides trigonometric (SIN, COS, TAN, etc.), inverse trigonometric, standard deviation (=STDEV), and logarithmic functions (=LOG(x,y)).

Unlock Excel's Full Potential

Excel boasts over 450 functions. Leave the calculator behind and harness the power of Excel for all your computational needs!
