Slide 6 - Slide

Simplifying - Please write along.
Simplify these expressions:
6a7b=42ab
3x+4x=7x
3x+7x3x=x
5xy+4xy=9xy
15ab+40ac=k.n.
73pq=21pq

Slide 7 - Slide

Simplifying - First on your own, then we'll discuss
Simplify these expressions:

Slide 8 - Slide

Simplifying - First on your own, then we'll discuss
Simplify these expressions:
2y5y=10y2
8y6y=2y
3b8a=24ab
6p+7pp=0
4m+12=n.p.
2abc+18abc=16abc

Slide 9 - Slide

Simplifying - Please write along.
Simplify these expressions:

Slide 10 - Slide

Simplifying - Please write along.
Simplify these expressions:
4x5y+7x+3y=4x+7x5y+3y
3a5b9ba=15ab9ab=6ab
2x8y+7x3y=16xy+21xy=37xy
=11x2y

Slide 11 - Slide

Worktime
You work neatly by…
  1. … reading the theory (again) before asking a question to your classmate.
  2. raising a hand before asking a question to the teacher.
  3. … if the teacher is busy, remember your question and move on.
