### Improve Competency with MyMathsHero

In this topic, we cover the revision of the following: Fraction, ratio and proportion, simple and compound interest, matric and latitude and longitude, sets and others. At the end of this topic, students should understand the following among other things:

• Theory of logarithm,
• Use and apply laws of logarithm to simplify and evaluate given expressions without the use of logarithm tables,
• Use log tables for calculation
• Express statements given in index form as an equivalent logarithm statement,
• Understand the equivalence between the laws of indices and the laws of logarithm.
• Use the simple and compound interest formulae,
• Calculate the simple and compound interest on a given principal at a given rate over a given period of time,
• Understand the use and definition of lines of longitude and latitude on the surface of the Earth,

Ans among others.
