![]() The values that make the equation true, the solutions, are found using the properties of real numbers and other results. The equation is not inherently true or false, but only a proposition. ![]() The expressions can be numerical or algebraic. In general, all the arithmetic operations can be performed on these numbers and they can be represented in the number line, also. In the following video we present more examples of how to evaluate an expression for a given value.Īn equation is a mathematical statement indicating that two expressions are equal. Real numbers are simply the combination of rational and irrational numbers, in the number system. If the algebraic expression contains more than one variable, replace each variable with its assigned value and simplify the expression as before. Replace each variable in the expression with the given value, then simplify the resulting expression using the order of operations. To evaluate an algebraic expression means to determine the value of the expression for a given value of each variable in the expression. When that happens, the value of the algebraic expression changes. In each case, the exponent tells us how many factors of the base to use, whether the base consists of constants or variables.Īny variable in an algebraic expression may take on or be assigned different values. The numbers we use for counting, or enumerating items, are the natural numbers: 1, 2, 3, 4, 5, and so on. In this section we will explore sets of numbers, perform calculations with different kinds of numbers, and begin to learn about the use of numbers in algebraic expressions.
