Students can go through AP Board 7th Class Maths Notes<\/a> Chapter 10 Algebraic Expressions to understand and remember the concepts easily.<\/p>\n

AP State Board Syllabus 7th Class Maths Notes Chapter 10 Algebraic Expressions<\/h2>\n

\u2192 Variable: It takes different values.
\nEx: x, y, z, a, b, c, m etc.
\nConstant: The value of constant is fixed.
\nEx: 1, 2, \\(\\frac{-2}{3}\\), \\(\\frac{4}{5}\\) etc.<\/p>\n

\u2192 Algebraic Expression: An algebraic expression is a single term or a combination of terms connected by the symbols ‘+’ (plus) or(minus).
\nEx: 2x + 3, \\(\\frac{2}{5}\\)p, 3x – 1 etc.<\/p>\n

\u2192 Numerical Expression : If every term of an expression is a constant term, then the expression is called a Numerical expression.
\nEx: 2 + 1, -5 \u00d7 3, (12 + 4) \u00f7 3.
\nNote: In the expression 2x + 9, ‘2x’ is an algebraic term. ‘9’ is called numeric term.<\/p>\n

\u2192 Like terms are terms which contain the same variables with the same exponents.
\nEx: 12x, 25x, -7x are like terms.
\n2xy2<\/sup>, 3xy2<\/sup>, 7xy2<\/sup> are like terms.<\/p>\n

\u2192 Coefficient: In a.xn<\/sup>, ‘a’ is called the numerical coefficient and ‘x’ is called the literal coefficient.
\nTypes of algebraic expressions.
\n\"AP<\/p>\n

\u2192 Degree of a monomial: The sum of all exponents of the variables present in a monomial is called the degree of the term or degree of the monomial.
\nEx: The degree of 9x2<\/sup>y2 <\/sup>is 4 [\u2235 2 + 2 = 4]
\nNote: Degree of constant term is zero.
\nThe highest of the degrees of all the terms of an expression is called the degree of the expression.
\nEx: The degree of the expression ax + bx2<\/sup> + cx3<\/sup> + dx4<\/sup> + ex5<\/sup> is 5.<\/p>\n

\"AP<\/p>\n

\u2192 The difference between two like terms is a like term with a numerical coefficient equal to the difference between the numerical coefficients of the two like terms.
\nNote:<\/p>\n

    \n
  1. If no two terms of an expression are alike then it is said to be in the simplified form.<\/li>\n
  2. In an expression, if the terms are arranged in such a way that the degrees of the terms are in descending order then the expression is said to be in standard form.<\/li>\n
  3. Addition (or) subtraction of expressions should be done in two methods, they are
    \ni) Column or Vertical method.
    \nii) Row or Horizontal method.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
