Definition of Monomial Monomial is one of algebra form that consists of one term. It is also defined as mathematical expression that consists of one term. The term is a number or the result of multiply between coefficient and the variables. Variable is symbol to replace unknown number yet. The general form is Difference between
Definition of Inequalities Inequalities is different with equality clearly. Equality use equal sign (=) but inequality use inequal sign (≠, >, <, ≤, ≥). Look at the table to understand about the inequality signs. Sign Meaning Example ≠ Not equals with … 1 ≠ 2 ≥ Greater than or equal to … a2+1 ≥ 10for
Algebra (“al-jabr”, from Arabic) literally meaning “reunion of broken parts”. Algebra is one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols. It includes everything from elementary equation solving to the study

Every function has each graph, but not all of the graph symmetric to x-axis, y-axis, or others. If the graph has symmetric, it concludes to specific case that the function is even or odd function. Even function and graph Even function is different mean with even numbers. The graph of even function is symmetric to
Previous topic about polynomial is multiplying. If there are two or more simple polynomial that are multiplied it will become complex polynomial. Concept of factoring polynomials is inversely. Starting from complex polynomial become simple polynomial. If the polynomial is divided by one of the simple polynomials then the remainder is zero. It is also called
When a triangle has a right angle (90°) and squares are made on each of the 3 sides, then the biggest square has the exact same area as the other 2 squares put together! Pythagoras Theorem can be written in one short equation: a2 + b2 = c2 Where: c is the longest side of the triangle
x Intercept is where the graph of an equation crosses the x-axis y Intercept is where the graph of an equation crosses the y-axis How To find the intercepts What Intercept Steps x intercepts (x, 0) 1. Set y=02. Solve for x y intercepts (0, y) 1. Set x=02. Solve for y Learn More General
To simplify a square root, make the number inside the square root as small as possible. How to Simplifying Square Roots Rule where a, b > 0 Simplifying Square Roots for Fractions Rule Surds Surd is a root we can’t simplify further. So √5 is a surd. But √9 = 3 is not a surd. Learn
Solving trigonometry’s problem that use right angle can be done by using right triangle and Pythagorean theorem. But, in other problems it does not use right triangle. It uses any triangles. The solution is using law of sines and cosines. It will be more complex than using right triangle but it does not mean difficult.
