OA 1 - Four Operation Review

Front

What is multiplication?

Back

Multiplication is a mathematical operation where a number is added to itself a certain number of times. For example, 3 × 4 means adding 3 four times (3 + 3 + 3 + 3 = 12).

Front

What is division?

Back

Division is a mathematical operation where a number is split into equal parts. For example, 12 ÷ 4 means splitting 12 into 4 equal parts, which equals 3.

Front

What is the equation to find how many items one person has if another person has a multiple of that amount?

Back

If one person has 'x' items and another has 'n' times that amount, the equation is: n × x.

Front

How do you find the total number of items when you know the number of packs and items per pack?

Back

Multiply the number of packs by the number of items in each pack. For example, if there are 3 packs with 12 items each, the total is 3 × 12.

Front

What is the equation to find the remaining items after some are used?

Back

To find the remaining items after using some, subtract the used amount from the total. For example, if you have 60 apples and use 12, the equation is: 60 - 12.

Front

How do you distribute items equally into groups?

Back

To distribute items equally, divide the total number of items by the number of groups. For example, if you have 48 apples and 6 baskets, you would do 48 ÷ 6.

Front

What is the remainder in division?

Back

The remainder is what is left over after division when the numbers do not divide evenly. For example, 35 ÷ 4 equals 8 with a remainder of 3.

Front

What is a word problem in mathematics?

Back

A word problem is a mathematical question presented in a narrative form, requiring interpretation and problem-solving skills to find the answer.

Front

What does it mean to have 'times as many'?

Back

'Times as many' means to multiply the amount by a certain number. For example, if someone has 4 times as many baseball cards as another, you multiply the other person's amount by 4.

Front

What is the total number of items if you have a certain number and someone has a multiple of that?

Back

To find the total, add the two amounts together. For example, if Sam has 12 cards and Aly has 4 times that, the total is 12 + (4 × 12).
