• (2 + 4) + 3 x 8.1 = 16.2

Constant Calculations

• 2 + 3 = 5
• 4 + 3 = 7
• 1 - 2 = -1
• 2 - 2 = 0
• 2 x 3 = 6
• 2 x 4 = 8
• 6 + 3 = 9 (Note: OCR showed '2', corrected to '9' based on typical calculator logic)
• 9 ÷ 3 = 3

Power and Fraction Calculations

• 3 x 4 = 12
• 1 ÷ 5 = 0.2
• 1 ÷ (2 x 3 + 4) = 0.1
