# Operators

Math operators work just how you'd expect in Soulver:

Operator | Behaviour |

+ or plus | Adds numbers together |

– or minus | Subtracts the first number from the second |

× or * | Multiplies numbers together |

/ or ÷ | Divides the first number by the second number |

^ or ** | Raises the first number to the power of the second number |

Soulver uses SI notation for large numbers. For instance, `10k`

is interpreted by Soulver as `10,000`

(ten thousand).

### Notation symbols for large numbers

Symbol | Name | Decimal |

k | thousand | 1,000 |

M | million | 1,000,000 |

G | billion | 1,000,000,000 |

T | trillion | 1,000,000,000,000 |

### Underscore as Grouping Separator

You may use an underscore character to separate numbers. This is commonly supported in programming languages, so you can easily copy and paste numbers between Soulver and your code
