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                                          E – 28 = 91

 

 

 

 

 

 

17G = 323                                            K ÷ 11 = 29

 

 

 

T – 82 = –230                                      R + 19 = 16

 

 

 

9F = –459                                            –19K = –323

 

 

 

And now, your final challenge

 

4A + 10 = 158                                                  5B + 28 = 603

 

 

 

 

 

–19H – 11 = 217                                              25K + 15 = –360

 

December 22, 2022

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

7B FL preparation questions

 Financial Literacy Preparation1)    I have $2500 in my account and it earns 2.75% of interest per year

Step 1: 2.75/100 = 0.0275

Step 2: 2500 x 0.0275 = $68.75

-       How much interest will I earn by the end of the year ($68.75)

-       What is the total? ($2568.75) 2500 + 68.75 = 2568.75

 

2)    In February 2023, Kwok will buy a Starbucks everyday. If the first ten TAPS are free, and he has to pay $0.75 for each additional TAP, how much will he pay? ($13.50)

28 days in Feb 2023

Kwok has to pay for 28 – 10 =18 TAPS

18 TAPS x 0.75 = $13.50

 Math test tomorrow. Open book, bring computer and calculator

Want an A+ in the test? Try to solve this compound interest question in Sheet

Batman bought his bat mobile for $655000. He will spend the next five years paying off his vehicle, and Batman will be charged an annual interest rate of 8.00%. The interest will be compound daily.

How much will he end up paying after five years. Use Sheet to calculate the answer.

hint:

- convert 8% into daily interest rate

- how many days in five years

Formula:

how much is borrowed x (1 + daily interest )^days in five years
