How Well Do You Know Arithmetic Operations?

Since 4 pineapples were removed from the table, only one pineapple is left on the table.

The question states that there are initially 5 cars parked in the lot. The dealer then brings 2 more cars. Therefore, the total number of cars in the lot is 5 + 2 = 7.

Subtraction is the mathematical operator used to remove one quantity or number from another. It involves finding the difference between two numbers by subtracting the smaller number from the larger one. This operation is commonly used in various mathematical problems, such as finding the change in quantities, determining the distance between two points, or calculating the result of a comparison. Subtraction is denoted by the minus sign (-) and is the opposite of addition.

The operation described in the question, where x and y are added together y times, is known as multiplication. Multiplication combines multiple quantities into a single quantity by repeatedly adding a number to itself a certain number of times, as indicated by the value of y.

When a group of 2 boxes is combined with another group of 3 boxes, the total number of boxes will be the sum of the two groups, which is 2 + 3 = 5. Therefore, we have 5 boxes in total.

The operator that combines two numbers or quantities into one is called addition. Addition is the process of combining two or more numbers to find their total or sum. It is represented by the "+" symbol. When you add two numbers, you are essentially putting them together to get a larger quantity. Therefore, addition is the correct answer in this case.

Division is the correct answer because it is the mathematical operation that allows for a quantity to be split into smaller values. When dividing a number by another, it is essentially splitting the original quantity into equal or smaller parts. This is different from subtraction, which involves taking away a certain amount from a quantity, and extraction, which is not a recognized mathematical operation.

To count four groups of two boxes, we can simply add the groups together. Since each group has two boxes, adding four groups together would give us a total of 8 boxes.

If there are 7 apples on the table, adding as many oranges as times the number of apples will give us 7 oranges. This means that for each apple, we add one orange, resulting in a total of 7 oranges.

Start with the initial number of empty spaces: 40 total spaces - 7 cars = 33 empty spaces.

Subtract the cars that left: 33 empty spaces + 3 cars = 36 empty spaces.

Subtract the cars that arrived: 36 empty spaces - 5 cars = 31 empty spaces.

Subtract the spaces used by the truck: 31 empty spaces + 2 spaces = 33 empty spaces.

Therefore, there are 27 empty parking spaces.
