Inequality : An inequality is a statement that contains an inequality sign between two expressions.

Subtraction : Subtraction is the mathematical operation that describes decreasing a number by an amount equal to a second number. The mathematical symbol for subtraction is the minus sign $-.$ The term subtraction is also used for a generalization of this basic operation on numbers to functions, vectors and matrices.

Subtract 1 from both sides of the inequality.

Addition : Addition is the mathematical operation that describes increasing a number by an amount equal to a second number. The mathematical symbol for addition is the plus sign $+.$ The term addition is also used for a generalization of this basic operation on numbers to functions, vectors and matrices.

Inequality : An inequality is a statement that contains an inequality sign between two expressions.

Calculate $1\cdot1+2.$

Inequality : An inequality is a statement that contains an inequality sign between two expressions.

Inequality sign : The word inequality sign refers to any of $\lt,$ $\gt,$ $\leq$ and $\geq.$

Multiplication : Multiplication is the mathematical operation that is a shorthand for adding the same amount several times. For example $3\cdot 4=4+4+4=12.$

Negative : A number is negative if it is $\lt 0.$

Number : A number $x$ is a mathematical symbol representing a quantity.

Multiply both sides of the inequality by -4. Take into account that multiplying an inequality by a negative number reverses the inequality (If one number is bigger than a second number, a negative number multiplied by the first number will be smaller than that negative number times the second number).
