No. 7*3, alone, is bigger than 12.

it wouldn't equal anything its a prime number but of course it would be only 2x1

It is: 1*2 = 2 which is also a prime number

3x1000 + 6x100 + 1x10 + 2x1/10 + 1x1/1000 = 3000 + 600 + 10 + 0.2 + 0.001 = 3610.201

One way to solve this system of equations is by using matrices. Form an augmented matrix in which the first 2x2 matrix is the coefficient matrix and the 2x1 matrix on its right is the answer. Now apply Gaussian Elimination and back-substitution. Using this method gives x=5 and y=1.

There is no number that if you multiply it by the same number will equal 2. only 2x1 is the only multiplyed number that will equal 2.====================================You both might like to play around with 1.414214 for a while.

3x1000 + 6x100 + 1x10 + 2x1/10 + 1x1/1000 = 3000 + 600 + 10 + 0.2 + 0.001 = 3610.201

118x12 equals 354+1118X 12====236+118====3541. 8x2 is 16.2. You bring the 1 to 2x1.3. 2x1 is 2, add the 1 which is 3.4. Then you multiply 2x1 again which is 2.NOW YOUR ON THE ROW...1. Add the magic 0.2. Multiply 1x8=8.3. Then you will multiply 1x1 which is 1.4. Last but not least you Multiply 1x1 again, and it equals 1.5. NOW YOU ADD ALL THAT UP AND YOU GET 354

22 + .056

2x (1+3)=(2x1+(2x3)
