The Use of Algebra in our Daily Life. 1. Algebra is a method of calculating using simple equations to represent quantity and to show relation between them. Algebra is also a part of our life‚ we use it on measuring the length of our table‚notebooks‚doors and other more. Another concept of mine is measuring capacity‚In school we always measure the right amount of ingredients that we cook.

What is Chemistry? Chemistry is the study of matter and energy and the interactions between them. This is also the definition for physics‚ by the way. Chemistry and physics are specializations of physical science. Chemistry tends to focus on the properties of substances and the interactions between different types of matter‚ particularly reactions that involve electrons. Physics tends to focus more on the nuclear part of the atom‚ as well as the subatomic realm. Really‚ they are two sides of the

Chemistry and Us The world is surrounded by so many things and everything is made of chemicals. Chemistry is very vital because it helps us to know the composition and changes of matter. Every single day of our life passes through chemistry in many ways. Human body works through the chemical reactions happening inside it. When we breathe‚ eat and sleep there’s still the presence of chemistry. The oxygen and foods we take helps our body to work. Exchanges of gasses‚ breaking down of foods we
