-5 (negative five) !
-5 - (-5) = 0
5 - 5 = 0
-5...
x2-2x-10-5 = 0 x2-2x-15 = 0 (x+3)(x-5) = 0 x = -3 or x = 5
15z² - 22z - 5 = 0 → (5z + 1)(3z - 5) = 0
0
0 - 5 = -5
minus 4 is bigger because minus 5 is further away from naught that minus 4 is
8
It could be: 5 minus 5 = 0 and 5 times 5 = 25
x3 - 3x2 - 9x - 5 = 0 (x + 1)(x2 - 4x - 5) = 0 (x + 1)(x - 5)(x + 1) = 0 x ∈ {-1, 1, 5}
1250 minus 800 equals 450. This can be calculated by subtracting the hundreds, tens, and units places separately, starting from the right side. In this case, 0 minus 0 is 0, 5 minus 0 is 5, 2 minus 8 is -6, which requires borrowing 1 from the hundreds place to make it 12 minus 8, resulting in 4.
