Harder BEDMAS
Part E: BEDMAS with negative integers (5 points each)
Hints: Follow this order, (first) bracket, exponents, division, multiplication, addition, subtraction (last)
(–3)3 + 30 ÷ (–6) + 12 + 22 – 13 + 15 + (–5)2 [ans: 11]
(–11) + 27 – 52 × 2 + 39 ÷ 3 – (–5) + 13 + (–2)3 [ans:–65]
Part F: Negative integers and simple algebra
Find the value for the following variables. Show all steps.
C + 53 = 88
17G = 323
T – 82 = –230
9F = –459
And now, your final challenge
4A + 10 = 158
–19H – 11 = 217

Bring food, fork, cup, plate for the luncheon please
(enough for 3 to 4 people)
Part A: Exponents
25 = 2 × 2 × 2 × 2 × 2
=32
63 = 6 × 6 × 6
= 216
Expand the following. Show your steps.
24 53 44 102
73 35 92 83
By definition, anything to the power 0 equals to 1.
e.g.
Kwok0 = 1
Part B: Square roots
We can use square roots when we try to find the answer to a number for which two identical number multiply by each other. For examples,
√49 = 7 because 7 x 7 = 49
Your calculator should have the square root function (√)
Find the square roots of the following numbers. Use your calculator.
64 121 196 841 1369 2809
Part C: Applications of exponents and square roots
If the area for a square is 81cm2, what is the length?
√81 = 9cm (The length is 9cm)
If the length for a square is 15cm, what is the area?
15 x 15 or 152 = 225cm2
Calculate the length of these squares if the areas are:
100cm2 169cm2 441cm2 2601cm2
Calculate the area of these squares if the lengths are: Use exponents
17.3cm 28.8cm 30.5cm 51.7cm
Basic order of operations with square roots and exponents
- Step 1: calculate the exponents and square roots first
- Step 2: then calculate the multiplication and division
e.g. 62 x 53 x 12 54 ÷ 51 x 23
= 36 x 125 x 1 = 625 ÷ 5 x 8
= 4500 = 1000
Calculate
92 x 33 x 22 43 ÷ 22 x 34 142 ÷ 22 x 25 102 ÷ 52 x 22
