Let's try solving multiplication table problems. Look at this table.
What does the table tell us? The table tells us the costs of 1 umbrella and 1 raincoat. An umbrella costs $7, while a raincoat costs $9. The second column in this table asks us to figure out how much 5 umbrellas and 5 raincoats cost. So how do we find these two numbers?
If 1 umbrella costs $7, 5 umbrellas cost 5 times $7. How do we write the multiplication problem for this? We write 5 times 7 (5 x 7). We get 35. The cost of 5 umbrellas equals $35.
How about the cost of 5 raincoats? If a raincoat costs $9, then 5 raincoats cost 5 times $9. Again, we write 5 times 9 (5 x 9). What's the answer? Five raincoats cost $45. Now we can write the answers in our table.
The last column in this table asks for the costs of 15 umbrellas and 15 raincoats. Let's solve again.
If 1 umbrella costs $7, 15 umbrellas cost 15 times as much. How do we write the multiplication problem for this? This time, we write:
The product, or answer, equals 105. The cost of 15 umbrellas is $105. How about for 15 raincoats? A raincoat costs $9. Therefore, the multiplication problem we have for 15 raincoats is:
The cost of 15 raincoats is $135. Finally, our table is complete.
