A decimal is a number expressed in the scale of tens. Commonly speaking we talk about decimals when numbers include a decimal point to represent a whole number plus a fraction of a whole number (tenths, hundredths, etc.). A decimal point is a point or dot used to separate the whole part of a number from the fractional part of a number.
This week, lets understand how to subtract fractions. To do so, make sure the bottom numbers (the denominators) are the same. Subtract the top numbers (the numerators). Put the answer over the same denominator. Simplify the fraction (if needed).
To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one.
Exponent Rules (Part 1)
In the previous tutorial, we learned about the Exponents. There are several laws of exponents (sometimes called “rules of exponents”) we can use to simplify expressions that include numbers or variables raised to a power. In this tutorial, we are learning these important rules of Exponents.
Exponent Rules (Part 2)
In this part we are learning about the Power Rule, which is a property of exponents that basically states that for any value to an exponent, which is then all raised to another exponent, you can simply combine the exponents into one by just multiplying them.
Exponent Rules (Part 3)
In this part we are learning about the Product Rule. The exponent rule for multiplying exponential terms together is called the Product Rule. The Product Rule states that when multiplying exponential terms together with the same base, you keep the base the same and then add the exponents.
Exponent Rules (Part 4)
In this tutorial, we are looking at the Rule of one. This rule says, when an exponent is 1, the base remains the same. First Any number raised to the power of “one” equals itself. This makes sense, because the power shows how many times the base is multiplied by itself.
Exponent Rules (Part 5)
In this tutorial we are learning what is a negative exponent, negative exponent helps to show that a base is on the denominator side of the fraction line. In other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa.
