Not necessarily.
What is your problem?
Needing to write an algebraic expression, 14 less than the quantity k times 6
Then another one, I don't understand the books answer, 35 multiplied by the quantity r less 45
6k - 14
35r - 45
35 multiplied by the quantity r less 45
6k-14

No, the terms "quantity of" and a multiplication problem are not the same thing, but they can be related.
The phrase "quantity of" is used to describe the amount or number of something. For example, if you have a bag of oranges and you want to know the quantity of oranges in the bag, you are asking about the number or amount of oranges.
On the other hand, a multiplication problem is a mathematical operation where you combine two or more numbers to find their total product. Multiplication is denoted by the symbol "×" or "*", and it involves multiplying the multiplicand by the multiplier. For example, if you multiply 4 by 3, the answer is 12.
However, there is a connection between "quantity" and multiplication. When you have a certain quantity of items and you want to find the total number of items, you can use multiplication. For example, if you have 5 bags, and each bag contains 6 oranges, you can find the total number of oranges by multiplying the quantity of bags (5) by the quantity of oranges in each bag (6), resulting in 30 oranges.
So, while "quantity of" and multiplication are not the same thing, multiplication can be used to calculate the total quantity of items in certain situations.
