These lectures are provided here for those who have not used math for awhile and need to brush up. We assume no previous level to begin, and so at the beginning. Skip...fast forward as needed.
These lectures are the property of Math Antics, this hopefully will take a little of the boredom out of the subject matter.
This is a very rudimentary introduction to the process of mathematics, add, subtract, multiplication and division. This is a good review for adults who want to sharpen their mindset for more advanced math subjects.
This lecture covers the basics of the rules of math governing the order that you execute the different operators in a mathematical expression, which comes first, add, subtract multiply or divide.
Whereas Add, Subtract, Multiply and Divide are operations involving at least two numbers, Factoring is an operation on one value or number. It is the methodology of breaking down one number or value into smaller numbers that when multiplied will equal the number that you are "Factoring". This is extremely valuable when working with fractions. You will see.
Add, subtract, multiply and divide are operations with more than one number. Factoring is on operation on a single number, breaking it down into the smallest whole numbers that when multiplied together equals the number that you "factored". Prime factors are factors that cannot themselves be factored beyond their value and the number "1".
Although adding single digit numbers is relatively easy, you could do it visually or with your fingers and toes, working with larger whole numbers requires a logical procedure. That is the subject of this lecture.
Subtraction of one whole number from another is slightly more complex, in that you must stack the two values in the proper order.
Multiplying a single digit number by another single digit number is well covered in the multiplication table or as we called it when we were children, the times table. This lecture discusses the procedure of multiplying whole numbers each with more than one digit or even a multi-digit multiplied by a single digit.
Multi-digit multiplied by another multi-digit, continued from Part #1.
With multiplication we introduced a step by step procedure to accomplish the result. Division of multi-digit numbers involves a procedure that is a little more complex. After listening to this lecture, you might want to repeat the two previous lectures on multiplication and this lecture immediately following.
Dividing a single digit number by a single digit number is really easy, save the remainder if you are allowing decimal fractions. However division with multiple digit numbers is a very tight procedure, once learned it not forgotten.
Negative numbers only make sense on the number line. This is very important if you are pursuing a technical skill.
This is more complex because we now have negative numbers in the operation. Slow down and repeat this lecture until you feel comfortable explaining it to another person.
Again, we have added negative numbers into the operations. But... The process is simpler than it was with addition and subtraction.
Exponents imply a certain type of operation, they tell you what to do with that number. Like tell you to multiply it by itself a certain number of times. I.E.... 2x2x2x2 or 2 with an exponent of 4.
The inverse of an exponent operation on a number is to take its "root", like working backwards from the result of applying an exponent.
