A multiplication sentence is a complete mathematical statement that shows a multiplication operation. It has three main parts: the factors and the product, connected by an equal sign.
Think of a multiplication sentence like a complete thought. It must have all its parts to make sense, just like a sentence needs a subject and a verb.
Sometimes, one number in a multiplication sentence is missing. Your job is to find the missing factor or product that makes the equation true. The equal sign (=) means the value on the left must balance with the value on the right.
The equal sign is like the center of a scale. Both sides must have the same total value, even if a number is hidden.
When a factor is missing, you can use related division or think of it as a "think multiplication" problem. Ask yourself: "What number multiplied by the known factor gives the known product?"
Multiplication and division are inverse operations. If you know your division facts, you can use them to find missing factors quickly.
Some problems show two multiplication expressions that must be equal. First, find the product for the complete side. Then, find the missing factor on the other side that gives the same product.
Always solve the complete side of the equation first. This gives you the target number you need to match on the other side.
Recognizing number patterns and properties of multiplication can help you solve problems faster and check your work.
After you find a missing number, plug it back into the original sentence. Does it make the equation true? This is the best way to check your answer.
