(-2) – 2 To find the value of 3y all we must do is add 1,470 and the negative factor of 2x (–2x) + 1,470 = {3y} Let “/” represent a fraction. Now we are going to find the value of 3y/3 (–2x/3) + (1,470/3) = {3y/3} Then we are going to find the value of Y (–2x/3) + 490 = {y} For this word problem, after following the steps to find it, the Y-intercept is {490} and the slope is {-2/3x} Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.
Like terms? Numbers that multiply together to get another number. Like terms are variables that are the same. Example: x-5x-5= 1 because x-5 and x-5 are like terms, meaning they factor out to one over one which is equivalent to one. -What are factors?
-x \) And \( \ r(x) = x \) Using the inverse steps introduced in Task 1a the process will be as follows \( \ r(x) = -x \)

3.OA.4 Determine the unknown whole number in a multiplication or division equation relating three whole numbers. A number multiplied by twelve makes thirty six. What is this number? 2 3 12 8 I think of a number, multiply it by eight, and I get thirty two.
Basic Operators Besides assigning a variable an initial value, we can also perform the usual mathe- matical operations on variables. Basic operators in Python include +, -, *, /, //, % and ** which represent addition, subtraction, multiplication, division, floor divi- sion, modulus and exponent respectively. Example: Suppose x = 5, y = 2 Addition:
x4 + 21x2 − 100. 2. Determine how many, what type, and find the roots for f(x) = x3 − 5x2 − 25x + 125. 3.
Reading this question, I experienced a high level of mathematics anxiety, I realised I could solve this question however I hesitated. I was contemplating ‘how I was going to communicate and explain my thinking?’ Initially to solve this question I utilised ‘the order of operations’, this is a knowledge I previously developed and indicates ‘multiplication and division are always completed before addition and subtraction’ in mathematics. I referred to a text book to extend my understanding, and according to Van de Walle (2010), ‘the power of two’ is an exponent which in this question is merely a shorthand interpretation for repeated multiplication of a number, times by itself.
Represent verbal statements of multiplicative comparisons as multiplication equations. Multination can be thought as two qualities that are that represent the multiple of the number. Until now students have focus on finding the difference between to two numbers. Learning about multiplicative comparison will help them compare two quantities by showing that one of the quantities is a number large than the other. For example, students can understand that 20 is 4 times larger than 5, and 20 is 5 times larger than 4.
In Math, Scott is working on developing a strategy to help him solve one-digit and two-digit multiplication problems. He has been exposed to the Bow-Tie method for two-digit, grouping and the array strategy for one-digit multiplication. He is doing very well at understanding and using the method to assist him in solving the multiplication problems. There have been improvements in his assessments by creating a strategy that works for him. After Scott has used the strategy over time, he will develop automaticity for solving the multiplication.
Guided Practice PERFORMANCE TASK(S): The students are expected to learn the Commutative and Associative properties of addition and subtraction during this unit. This unit would be the beginning of the students being able to use both properties up to the number fact of 20. The teacher would model the expectations and the way the work is to be completed through various examples on the interactive whiteboard. Students would be introduced to the properties, be provided of their definitions, and then be walked through a step by step process of how equations are done using the properties.
o Mental math: 20 ÷ 2 (10) Step 2: Solve • Have students solve the division problem using long division for the 1st problem and mental math for the second problem on their chalkboards. Remind students to show all their work for the first problem. • Walk around and check for understanding, ask guiding questions to help students who might need further assistance. • When students have solved the problem, ask students to raise their chalk boards to show you their answers. If correct, students may erase their work.
Math is often one of the hardest subjects to learn. Teachers know rules that can help students, but often they forget that those rules become more nuanced than presented.
Module 0 | Unit 1: The Language of Algebra Key Concepts: Expressions, operations on real numbers, and exponents and roots Essential Questions: How can you use variables, constants, and operation symbols to represent words and phrases? How do you add and subtract real numbers? How do you multiply and divide real numbers?
I highly recommend this website as it has helped me in my own work in math. I sometimes have trouble catching on to the concepts of math problems, and Khan Academy’s way of working it out helps me immensely. MathPlanet Well organized and explained,
