A positive integer is a whole number greater than zero, and a negative integer is a whole number less than zero. Whole numbers are numbers without any fractions or decimals. These numbers are also called counting numbers.
Know MorePositive and negative integers have many uses in real life. The negative integer -16 may be used to describe a loss of $16 or 16 pounds. The positive integer +5 might be used to refer to a gain of 5 pounds. These numbers are also used with temperatures. The positive integer +32 is another way to say it is 32 degrees above zero, while the negative integer -3 is used to say it is three degrees below zero.
Learn MoreA formula equation is a visual representation of a reaction using chemical formulas. A chemical formula is an expression that states the number and types of atoms that make up any given molecule using the symbols for the elements and sub-scripted numbers.
Full Answer >A polynomial function is a mathematical function that consists of one or more variables to which multiple exponents and coefficients are applied. Each combination of variables, exponent and coefficient is called a term. A polynomial does not contain any negative exponents, radical variables or division of any kind, including fractions.
Full Answer >A unitary matrix is a matrix that when multiplied by its complex conjugate transpose matrix, equals the identity matrix. This implies that the complex conjugate transpose of a matrix is equal to the inverse of the unitary matrix. Unitary matrices have several applications in different fields of science and engineering, such as quantum mechanics.
Full Answer >A real-life example that uses slope is determining how someone's savings account balance has increased over time. When determining the rate at which the account has increased, the account owner is calculating the slope of the line that shows the changes in the account's balance.
