Do big numbers go on top when multiplying?
It’s a good habit to always write the larger number on top. The problem will be harder to solve if you don’t. Next, write the times sign to the left of the numbers. Always set up stacked multiplication problems the same way: with the larger number on top… and the right digits lined up.
How do you read large numbers on a calculator?
On a calculator display, E (or e) stands for exponent of 10, and it’s always followed by another number, which is the value of the exponent. For example, a calculator would show the number 25 trillion as either 2.5E13 or 2.5e13. In other words, E (or e) is a short form for scientific notation.
How do you simplify large mixed numbers?

How do you simplify odd numbers?
To simplify an improper fraction, you must turn it into a mixed number, which includes a whole number and a fraction together. The number of times you can divide the numerator evenly by the denominator will be the whole number of your mixed number. Write this number down, and note the remainder.
