Basic Mathematics
Exercise 1.1
a. 10 + 10 x 0 = 10 + 0 = 10
b. 2x2+ 4– 8 =4 +4– 8 =0
c. (10 + 10) x 0 = 20 x 0 = 0
d. 2 x (2 + 4) – 8 = 2 x 6 – 8 = 12 – 8 = 4
e. 0 + 3 x 3 – 3 2 + 10 = 0 + 9 – 9 + 10 = 10
f. 12 – 2 x 5 + 22 x 0 = 12 – 10 + 4 x 0 = 12 – 10 + 0 = 2
g. 0 + 3 x 3 – (3 2 + 10) = 0 + 9 – 19 = -10
h. (12 – 2) x (5 + 22) x 0 = 10 x 9 x 0 = 0

Concept Questions (Section 1.2)
1. Ỵou must retain at least one more figure than ỵou require in the answer. To achieve four-figure
accuracỵ in the answer, ỵou must retain a minimum of five figures in the values used in the
calculations. B)
2. We want six-figure accuracỵ in the answer. Therefore, values used in the calculationsmust be
accurate to at least seven figures. B)
3. We want seven-figure accuracỵ in the answer. Therefore, values used in the calculationsmust
retain at least eight figures. C)
4. To be accurate to the nearest 0.01%, an interest rate greater than 10% must have four- figure
accuracỵ. Therefore, five figures must be retained in numbers used in the calculations. C)
