Common Mistakes

Avoid these common errors when working with the number 10 in a calculator:

• Pressing "1" followed by "00" instead of "1" then "0" - this enters 100 instead of 10
• Forgetting to press the operation button (+, -, ×, ÷) before entering the second number
• Not clearing the calculator between calculations, which can lead to incorrect results
• Assuming the calculator will automatically multiply by 10 when you press the "×" button - you must enter both numbers
