Answer:
the product of a number and 45
Explanation:
When you see a number like 45 right next to a variable like "n", this means they are being multiplied!
"Product" means there is multiplication ( × ) happening
"Quotient" means there is division ( ÷ ) happening
"Sum" means there is addition ( + ) happening
"Difference" means there is subtraction ( - ) happening
Here are some examples:
30n ⇒ the PRODUCT of a number and 30
12÷n OR
⇒ the QUOTIENT of a number and 12
2 + n ⇒ the SUM of a number and 2
100 - n ⇒ the DIFFERENCE of a number and 100
