Mnożenie i dzielenie wyrażeń algebraicznych przez liczby - Matematyka S.P. i Gimnazjum

In this video, I show how to multiply and divide algebraic expressions by numbers. I explain how to multiply a monomial by a number while considering the signs, how to change the order of the factors, and how to multiply algebraic sums by numbers — including negative numbers and negative one. I also present the rules for dividing monomials by numbers and for dividing entire algebraic sums by numbers. Step by step, I explain how to perform these operations and how to simplify the results, including the reduction of algebraic fractions. Contents: 1. Reminder: 2 times a and a times 2 2. Multiplying a number by a monomial 3. Multiplying a number by a monomial containing a fraction 4. Multiplying a number by a mixed number 5. Multiplying a number by an algebraic sum 6. Multiplying by a negative number 7. Multiplying by negative one 8. Dividing a monomial by a number 9. Dividing an algebraic sum by a number 10.
