98 - 69 = 29
8n + 7 - n - 98 = 7n - 91
11111 - 11111011 = −11011100 or converted to decimal 31 - 251 = −220
9.090909e+96
2.83 to the nearest hundredth.
346 minus 251 is 95.
That would be 151.
It might be possible to work this in your head. Your 98 is 100 minus 2. This means 98 plus 98 is 100 plus 100 minus 2 minus 2. That's 200 minus 4 which gives 196 as the answer.
The atomic number of californium is 98. The atomic mass of the most stable isotope - 251Cf - is (251) after IUPAC.
98 - 69 = 29
8n + 7 - n - 98 = 7n - 91
15 - 98 = -83
8
Negitive 100
Californium's atomic number is 98. Thus, to be neutral, it must have 98 protons and 98 electrons. 251Cf is its longest lived isotope and has 251 - 98 = 153 neutrons.
2010 - 1912 = 98
472 - 374 = 98
