The result of adding or subtracting signed numbers.

The product of two negative numbers is always positive.

The product of a positive and a negative number is always negative.

When subtracting signed numbers with different signs, change the operation sign to plus and change the sign of the subtrahend.

Like multiplying signed numbers, division of signed numbers follows the same sign rules.

The quotient of two negative numbers is positive.

The quotient of a positive and a negative number is negative.

The quotient of a negative and a positive number is negative.

The number that's being divided.

The number that the dividend is being divided by.

The result of dividing one number by another.

Moving the decimal point in both the divisor and dividend to the right by the same number of places to make the divisor a whole number.

The number of digits after the decimal point in a number.

The product of the multiplicand and the multiplier.

A number that is multiplied by another number.

A number that multiplies another number.

Multiplying fractions involves multiplying the numerators (top numbers) and the denominators (bottom numbers).

Before multiplying fractions, look for common factors in the numerators and denominators, and simplify by dividing them out.

The word 'of' in fraction problems means 'multiply'.

To find the value of a complex fraction (fraction within a fraction), simplify the smaller fractions first and then perform the multiplication.

A fraction that represents a portion of a whole, often expressed as a numerator divided by a denominator.

A common fraction is in its lowest terms when the numerator and denominator have no common factors other than 1.

A value that represents a power of 10, often used to express very large or very small numbers.

Means 'one thousand', which is equivalent to 10 raised to the power of 3 (10³).

Means 'one hundredth', which is equivalent to 10 raised to the power of -2 (10⁻²).

Means 'one tenth', which is equivalent to 10 raised to the power of -1 (10⁻¹).

Means 'one millionth', which is equivalent to 10 raised to the power of -6 (10⁻⁶).

Means 'one billionth', which is equivalent to 10 raised to the power of -9 (10⁻⁹).

A standard unit of measurement for length, defined as the distance light travels in a vacuum in 1/299,792,458 of a second.

The decimal system uses powers of 10 to represent larger and smaller values. For example, 1 meter (m) is equal to 10 decimeters (dm), 100 centimeters (cm), or 1000 millimeters (mm).

The distance a light beam travels in a vacuum in 1/299,792,458 of a second. It is constant and used to define the meter.

A meridian quadrant is the distance from the geographic pole to the equator, roughly 1/4 of the Earth's circumference.

An alloy of platinum and iridium, was used as the standard for the meter until 1960.

The foot (ft) is the standard unit of length used in the US, unlike the metric system.

Measures are used to determine the exact size or distance of objects, like the length of a street or the length of a plane.

Units are the building blocks of measurement, like meters for length, grams for weight, or liters for volume.
