E: CONTENT
Revision of Whole Numbers
Example:
405,020,110
is read as:
Four hundred and five million, twenty thousand, one hundred and ten.
Revision of Binary Numbers
101₂ = 5₁₀
110₂ = 6₁₀
Revision of Place Value
In 326,415:
The place value of 2 is:
20,000
Revision of HCF and LCM
For 8 and 12:
Factors of 8:
1, 2, 4, 8
Factors of 12:
1, 2, 3, 4, 6, 12
HCF = 4
LCM of 8 and 12 = 24
Revision of Fractions
1/2 + 1/4 = 3/4
3/4 = 75%
Revision of Ratio
Simplify:
12 : 18
Divide both by 6:
2 : 3
Revision of Percentage
Find 25% of 200.
25/100 × 200
\= 50
Revision of Addition and Subtraction
4,250 + 3,150 = 7,400
8,000 − 2,750 = 5,250
Revision of Multiplication and Division
125 × 8 = 1,000
900 ÷ 30 = 30
Revision of BODMAS
Solve:
6 + 4 × 3
Multiply first:
4 × 3 = 12
Then:
6 + 12 = 18
