They are used in solving arithmetic’s / mathematics. Table arithmetic operations

+ | Addition | A = A + B | A = A + B |

– | Subtraction | A = A-B | A = A –B |

* | Multiplication | Y = 2* X | Y = 2x |

/ | Division | T = X*Y | T = xy/ |

^ or ** | Exponentiation | Y= X*B^2 | Y = XB2 |

Note that the Hierarchy of Arithmetic operations are in the order of

(i) Exponentiation

(ii) Negation

(iii) Multiplication

(iv) Integer division

(v) Modules arithmetic

(vi) Addition and subtraction.
