Algebraic Manipulation

Algebraic Manipulation

This chapter explores algebraic manipulation. It covers expanding brackets with common factors and changing the subject of a formula. Expanding brackets Suppose we wanted to expand and simplify;

Distance-Time Graphs

Distance-Time Graphs

This chapter covers distance-time graphs. It explores how to draw and interpret distance-time graphs. Having prior knowledge of gradient of a straight line and speed will be very useful here. What is kinematics Kinematics is the study of an objects [...]

Y=mx+c

Y=mx+c

In this chapter we’re going to be looking at y=mx+c graphs. We shall explore the effects of m and c on the line in the y=mx+c equation. We shall then explore how to find the equation of a line drawn [...]

Upper and Lower Bounds

Upper and Lower Bounds

In this chapter we’re going to look at upper and lower bounds. We shall explore numbers rounded to the nearest 10, 100 or 1 and work out the lowest and highest values of the original rounded values. World’s strongest man [...]

Quadratic Sequences

Quadratic Sequences

In this chapter we’re going to be looking at quadratic sequences. We shall explore how to find the nth term of a quadratic sequence. Here is a sequence; The differences between these terms in the sequences are not equal. This [...]

Multiplying Decimals

Multiplying Decimals

In this chapter we shall be looking at multiplying decimal numbers together. This should be straight forward and simple. Work out 0.6 x 0.8 To work out this easily we’re going to make the decimal numbers whole numbers first. To [...]

Mean

Mean

In statistics mean is defined as the average of the total of the numbers in the data. The mean of data is the total of all the data divided by the number of items in that data. Finding Mean Here [...]
