CALCULATOR PRACTICE

I) Arithmetic (Standard Calculator):

34 + 45 * 23 – 65 = _____________________

560.90 + 234.76 * 9 / 3.333 + 78.60= _____________________

213 + 0.000025 – 54.70 – 45 / 2.50= _____________________

27.40 * 34 + 90 – 54.70 – 45.000 / 2= _____________________

12 * 3 * 3 + 3 + 3.33 * 2.333 / 1.1= _____________________

45.36 – 25.6666 – 45.78 * 1.15 + 2= _____________________

II) ALGEBRA (Scientific Calculator):

48 * 537.9 + 34.90 – 10.13 * 78 + 2 ^ 3= _____________________

45 * (537.9 + 34.90 – 10.13) * 78 + (2 ^ 3)= _____________________

123 + 56.80 * 34 – 23.900 * (35 + 22.5784)= _____________________

(123 + 56.80) * (34 – 23.900) * 35 + 22.5784= _____________________

571 – 321.52 + 8 ^ 2 – 120.170= _____________________

(571 – 321.52 + 8) ^ 2 – 120.170= _____________________

(571 – 321.52) + 8 ^ 2 – 120.170= _____________________

(571 – 321.52) + ( 8 ^ 2) – 120.170= _____________________

(12 * 2) ^ 3= _____________________

12 * 2 ^ 3= _____________________
