To convert the number 11 in base 2 to base 10, you need to multiply each digit by 2 raised to the power of its position from right to left, starting at 0. In this case, the calculation would be 1 x 2^1 + 1 x 2^0, which equals 2 + 1, resulting in the base 10 equivalent of 11 in base 2 being 3.

Each place value column in base 2 is twice that of the column to its right.
→ 11₂ = 1 × 2 + 1 = 3 in base 10.
To subtract in base 2, we need to borrow from the next higher place value if necessary. In this case, when subtracting 11 from 101 in base 2, we need to borrow from the leftmost digit. So, 101 in base 2 is 5 in decimal, and 11 in base 2 is 3 in decimal. When subtracting 3 from 5 in decimal, we get 2 in decimal, which is 10 in base 2. Therefore, 101 base 2 minus 11 base 2 is 10 base 2.
To subtract 11 in base 2 from 100 in base 2, you first convert both numbers to decimal. 100 in base 2 is equal to 4 in decimal (12^2 + 02^1 + 02^0). Similarly, 11 in base 2 is equal to 3 in decimal (12^1 + 12^0). Subtracting 3 from 4 in decimal gives you 1 in decimal, which is equal to 1 in binary (12^0). Therefore, 100 in base 2 minus 11 in base 2 equals 1 in base 2.
Your question, "Is there any way 2 plus 2 can equal anything but 4?" My answeris YES. If you were to use base 3 math, 2 plus 2 would then equal "11" (base 3) 2 plus 2 = 11 (base 3)
Area of triangle = (1/2) x (base) x (height) In our case it is (1/2) x 11 x 5 = 55/2 = 27 and 1/2 square units
