In algebra, we replace a letter with numbers in the process known as substitution. Given the formula A = 1/2bh, if the base is 5cm and the height is 10cm, then the area is ½ X 5 X 10 because we have replaced the b with 5 and the h with 10. You just need to be be careful with negative numbers: it is
To find the equation of a straight line from a graph, you first need to find the gradient and then secondly find the y-intercept.
The equation of a straight line is y=mx+c, where m is the gradient and c is the y-intercept.

Continue learning about balancing equations, as a part of chemical calculations.
The law of conservation of mass states that no atoms are lost or made during a chemical reaction. There are different ways of arranging the atoms. Chemical reactions are about rearranging atoms.
