  • Addition is an operation indicated with + sign. The result of addition of two or more numbers (addends)is called their Sum

  • Subtraction is an operation indicated with a - sign. The result of a subtraction is called the difference.

  • Multiplication is an operation with * or dot or X or variables can simply be written together. The cross (X) is not normally used with literal numbers because it can be confused with the variable x. 5xy means 5 times x times y and is read 5 x, y. The result of a multiplication is called the product and the numbers that are multiplied together are the factors.

  • Division is an operation indicated by viniculum, slash or an obelus (÷) which is also know as a division sign. To divide x by y, where y is not zero, means to find a number z such that x = yz. x is called the dividend, y is called the divisor and z is called the quotient.
