2. multiplying 2 and 2 is the same as adding 2 and 2.
The answer is "double".
1 multiplied by 5 plus 2 equals 7. This is because you are multiplying 1 into 5 and then adding 2.
Depends what you mean by the "size" of the figure.To double the linear dimensions of the figure ===> Multiply the linear dimensions by 2.To double the area of the figure ===> Multiply the linear dimensions by sqrt(2). (1.4142)

because when you multiply by 2 you are just doubling the number being multiplied by two. example: 5x2=10 5+5=10
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.
2. multiplying 2 and 2 is the same as adding 2 and 2.
The answer is "double".
you multiply 5 by 2 which is ten or you think of adding 5 two's or adding 2 fives.
Multiplying by two is the same thing as adding the number to itsself again. 2 (4) = 4 + 4
multiply seven by 2 which is fourteen
As 5 = 10 ÷ 2: I usually multiply by 10 (by shifting the decimal point one digit to the right, adding a zero if it was originally at the end of the number) and then dividing by 2.
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
Adding negatives? You get a negative. But if you multiply/divide 2 negatives, that's a positive.
