How can adding doubles help you to multiply by 2 example?
Adding doubles can help you multiply by 2 through the property of commutativity in multiplication. By adding two equal numbers together (doubles), you are essentially multiplying one of the numbers by 2. For example, 5 + 5 = 10, which is the same as 5 x 2 = 10. This strategy can simplify multiplication problems and help build a deeper understanding of the relationship between addition and multiplication.
How does adding doubles help you multiply by two?
because when you multiply by 2 you are just doubling the number being multiplied by two. example: 5x2=10 5+5=10
How can adding doubles can help you to multiply by 2 give an example?
Mulitplying is really just a form of addition. Multiplying by 2 is the same as adding a number to itself (or adding doubles). For example: 4X2 is the same as 4 + 4 = 8 The X2 part of the multiplication problem means that you are adding doubles or 4 to itself. So any problem with X2 would be the same as adding doubles: 5X2 = 5 + 5 = 10 6X2 = 6 + 6 = 12 7X2 = 7 + 7 = 14 ...and so on. So if you can add doubles you already know how to multiply any number by 2.
Multiply a number by 2 to get the same answer as adding a....?
Multiplying by two is the same thing as adding the number to itsself again. 2 (4) = 4 + 4
How do you multiply 7 x 12?
Since 12=10+2 We first multiply 7 by 10 to get 70 and then 7 by 2 to get 14 adding these gives us our final answer: 84
