Large Numbers
Read the numbers properly. Remember to use "and" after hundreds (e.g., 3 456 → three thousand, four hundred and fifty six).
Note: Thousands and millions are separated only by spaces (e.g., 7 403 126).
Decimals
Decimal fractions are said with each figure separate. We use a full stop (called "point"), not a comma.
Example: 3.375 → three point three seven five.
Powers Reference
In 65, 6 is the base and 5 is the index or exponent.
It is read as: "six to the power of five" or "six powered to five".
Special cases:
32 → Three squared (or three to the power of two).
53 → Five cubed (or five to the power of three).
