Expression is the mathematical phrase made up of numbers and operations
An expression is made up of numbers and variables joined by mathematical operations.
A term, expression, equation or identity.
That type of sentence is called a mathematical expression.
It is an expression.
They do not apply to all expressions - only to those expressions whose elements are either real numerical constants or variables which can only take real values.The set of real numbers is closed under the operations of arithmetic. As a result each term in an expression, which will be made up of real constants or real variables, will also be a real constant or variable. And since each term in the expression is real, the closure implies that their combination is also real.
Numbers are made from numerals as for example numbers are made from the Hindu-Arabic numerals of 0 1 2 3 4 5 6 7 8 and 9
algabraic expression
each of the four numbers have 10 possibilities, and each of the three letters have 26 possibilities. so the total possible ways u can arrange them are 10x10x10x10x26x26x26 this totals up to 175,760,000 different license plate numbers
One. A term is made up of numbers and variables joined by multiplication or division.
What is a literal coefficient? Expressions are made up of terms joined by adding and subtracting. Terms are made up of numbers and variables multiplied together. In the term 3xy5, 3 is the (numerical) coefficient, and xy5 is the literal coefficient.
There are 24 number made by permutations of the digits. There are lots more if the digits can be repeated, for example, 27335722. Even more can be made by using arithmetic and algebraic operations, for example 35^27 = approx 4.8960*10^41. You have not specified what the rules for "making" numbers are!
