Algebra - Week 3 Lesson 1: Multiplying and Dividing Variables

Lesson:

This lesson will focus on reviewing last week's content (constructing expressions, simplifying expressions, expanding brackets) and introducing multiplying and dividing variables. 

MULTIPLYING VARIABLES

Ex 1: Multiplying different variables:
  • b x h = bh
  • the variables are written beside each other which tells us they are being multiplied together

Ex 2: Multiplying the same variables:
  • b x b = b2 (b squared)
  • you simply add the exponential values together
  • when a variable doesn't have an exponent that means it is to the power of 1
  • b3 x b5 = b8 (because 3 + 5 = 8)


DIVIDING VARIABLES

Ex 1: 25b / 5 = 5b
  • All you need to do is divide the coefficient (the number in front of the variable b) by 5.

Ex: b5 / b3 = b2
  • We are only going to focus on dividing terms with the same variables
  • You just need to take the exponential value of the first term and divide it by the exponential value of the second term (5 - 3 = 2, so the answer is b2)

Algebra - Week 3 Lesson 2: Solving Equations (One-step)

Lesson:

  • Equations contain an equal sign. The focus of this lesson is to isolate the variable on one side of the equation.

  • The can be done by using the  ‘change side, change sign’ rule.

  • We inverse (opposite) operations to cancel out the terms on the side with the variable. Whatever you do to one side, you must also do to the other side.


Ex 1:

  • a + 2  = 10

  • a = 10 - 2

  • a = 8
