What happens to the decimal point when multiplying a number by 10 raised to a power?

Back

The decimal point moves to the right for positive powers and to the left for negative powers.

How do you evaluate an expression with parentheses, such as 3 x [ (8 + 2) x (6 x 5) ]?

Back

First, solve the expressions inside the parentheses, then multiply the results according to the order of operations.

Front

What is the order of operations in mathematics?

Back

The order of operations is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), often abbreviated as PEMDAS.

Front

How do you convert a number in scientific notation, like 4.635 X 10^2, to standard form?

Back

Move the decimal point to the right by the number of places indicated by the exponent.

Front

What is the place value of a digit in a number?

Back

The place value of a digit is its value based on its position in the number.

Front

How do you find the coordinates of a point on a coordinate plane?

Back

Coordinates are given in the form (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What is the result of multiplying two numbers, such as 5 x [ (2 x 3) x (4 x 5) ]?

Back

First, calculate the products inside the brackets, then multiply the result by 5.

How do you determine the total value of an expression with multiple operations?

Back

Follow the order of operations (PEMDAS) to evaluate the expression step by step.

Front

What is the significance of the exponent in a power of ten?

Back

The exponent indicates how many places to move the decimal point when converting to standard form.
