An expression, or, more pedantically, inequalities.
You might mean an inequality (with 'less than', 'greater than', etc). You might mean an expression.
A mathematical expression has numbers and operation signs with no equal sign. Equations, on the other hand, do contain equal signs.
If two numbers have opposite signs, then their product and quotient are both negative.
There are infinitely many pairs and the answer depends on the operations. For example, 1+42 equals 43
algebraic expression consists of numbers and operations

Algebraic expression
If two numbers have opposite signs, then their product and quotient are both negative.
There are infinitely many pairs and the answer depends on the operations. For example, 1+42 equals 43
A mathematical phrase containing numbers and operations is called an expression. Expressions can be joined together with an equals sign to form an equation.
if there are no comparison signs (equals or inequalities, ie =, >, < etc) then it is an expression, eg "x + 5" If there is a comparison sign which is not equals, then it is an inequality, eg "x > 5"
algebraic expression consists of numbers and operations
The order of operations which equals 229 is (2000/10) + (50-21) =229.
All expressions combine numbers and operations!
A collection of things together with operations on those numbers and the properties that the operations satisfy or in other words, a collection of numbers together with operations, properties of the operations, and a system of representing these numbers.
You add all the numbers with + signs and subtract all that have minus signs.
