1x1=1
11
1x11=11
1x11 11 is prime. No tree.
it is the identity 1 times a number is that number the number keeps its identity 1x11=11
The easiest way to multiply by ten is to annex the zero 1x11=11 10x11=11 plus the zero on the end. 110
you can find that because the 10 comes after 11 so that make it eazy
1x11=11 2x11=22 3x11=33 4x11=44 5x11=55 6x11=66 7x11=77 8x11=88 9x11=99 10x11=110
1x1=1 1x2=2 1x3=3 1x4=4 1x5=5 1x6=6 1x7=7 1x8=8 1x9=9 1x10=10 1x11=11 1x12=12 thats all you need to know
For example, -1 times 11.
The simple rule is that 1 times anything is always the number you start with. For example: 1x0=0 1x1=1 1x2=2 1x3=3 1x4=4 1x5=5 1x6=6 1x7=7 1x8=8 1x9=9 1x10=10 1x11=11 1x12=12
11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121
Any positive value upto 36 square units. A 6x6 square will have the maximum area of 36 sq units; a 5x7 rectangle will have an area of 35 sq units, and the area will be reduced as you reduce one of the measures and increase the other so that their sum remains 12 units so that the perimeter is 24 units. 1x11 will be 11 sq units 0.1x11.9 will be 1.19 sq units 0.01x11.99 will be 0.1199 sq units 0.001x11.999 will be 0.011999 sq units, etc.
Since you are using integers, the first place to look would be if two sides are equal to 1 meter. Then the other two sides are 24/2 - 1 meter, or 11 meters. Once you know this, you can divide 24 by 4 (the 4 sides of a rectangle) to see that a square version of this rectangle is 6 meters. So, all of the possible dimensions (without reversed duplicates) go from 1 meter to 6 meters: 1x11 2x10 3x9 4x8 5x7 6x6
