May/June 2021 · Paper 1 · Number — order of operations

Work out.
(a) 74.6 × 10 − 3.89 × 100
(b) 5 + 3 × 2 − 1

Show model answer

(a) 74.6 × 10 = 746
3.89 × 100 = 389
746 − 389 = 357
(b) Multiply first: 3 × 2 = 6
5 + 6 − 1 = 10

Multiply before you add or subtract (order of operations).

May/June 2021 · Paper 1 · Geometry — angles in polygons

Quadrilateral ABCD has AD extended beyond D to a point E.
Angle BCD = 135°, angle BAD = 83° and angle CDE = 122° (the exterior angle at D, between DC and DE).
Angle ABC = x°.
Find the value of x.

Show model answer

Angle CDE is the exterior angle at D, so the interior angle ADC = 180 − 122 = 58°
The interior angles of quadrilateral ABCD sum to 360°:
angle BAD + angle ABC + angle BCD + angle CDA = 360
83 + x + 135 + 58 = 360
276 + x = 360
x = 84

Find the missing interior angle at D from its exterior angle, then use angle sum of a quadrilateral = 360°.

May/June 2021 · Paper 1 · Mensuration — area of a trapezium

Trapezium ABCD has parallel sides AB = 7 cm and DC = 10 cm. The area of ABCD is 85 cm². The perpendicular height of the trapezium is h cm.
Find the value of h.

Show model answer

Area of trapezium = (1/2)(a + b)h
85 = (1/2)(7 + 10)h
85 = 8.5h
h = 85 ÷ 8.5
h = 10

Use the trapezium area formula and solve for the height.

May/June 2021 · Paper 1 · Algebra — simplifying and expanding

(a) Simplify 6x + 15 − 2x + 8.
(b) Expand and simplify (x − 5)².

Show model answer

(a) 6x − 2x = 4x
15 + 8 = 23
Answer = 4x + 23
(b) (x − 5)² = (x − 5)(x − 5)
= x² − 5x − 5x + 25
= x² − 10x + 25

Collect like terms; expand a squared bracket by multiplying it out fully.
