How do you write an expression for the work phrase “q multiplied by 2”?

Hint: We are asked to write the phrase into an equation. To do so we will learn about the algebraic tool which is commonly used to do such conversion. We will learn when we use +, x, /, –. We will work with different examples. Once, we learn the application of this tool, then we will start our problem. We see that our problem has the word multiplication. So, we will look for the appropriate tool for this, and then we will convert our problem to an equation.

Complete step by step answer:
We are asked to convert the phrase “q multiplied by 2”. So, to do this we will learn how we will convert the expression to the equation and to do so we will have to learn about the algebraic tools. In Maths, we have various tools which we use to write or solve our problem. We have tools like +, –, x, /, etc. We will describe some basic ones to write our equation.
The tool + is used when we are asked that terms are being added up. For example, we have the addition of 2 and 4 is 4 means it is written as 2 + 4 = 6.
The tool – is used when we are informed about subtraction between two terms like if we are told that x is subtracted from y, then we write it as y – x.
If we have told that the terms are being divided up then we use \[\div \] this is called for the division of terms. Say if we have r divided by 2, so we will write it as \[r\div 2.\] Also, we can use \[\div \] as /. So, \[r\div 2\] is the same as r/2.
Now, lastly, we have ‘x’ this is used when we are given that the terms are being multiplied by one another. For example, if we are said 2 is multiplied by 10, then we will write it as \[2\times 10.\]
Now, in our problem, we have a phrase as “q multiplied by 2”. So, here we can see that the terms are called that they are being multiplied. So, we use \['\times '\] the tool. So, the expression for “q multiplied by 2” will be \[q\times 2.\]

Note:
 We need to be very careful while changing the phrase to the equation. We need to have knowledge about each word, what it means in terms of algebra, then only we can form our equation. There are different terms with the same meaning. The sum is the same as addition, the product is the same as multiplication and many more and we have to choose correctly.
