-25 - 10 = -35
Minus 25 (5x5=25 if there is one minus then the answer is minus).
25 minus 35 is -10.
-10 - 15 = -25
25 - 5 = 2020 - 5 = 1515 - 5 = 1010 - 5 = 55 - 5 = 0Therefore 5 can be subtracted 5 times from 25.
-25 - 10 = -35
Minus 25 (5x5=25 if there is one minus then the answer is minus).
25 minus 35 is -10.
(4 x 25 + 1) x 10
25 times 6 times 25 minus 8 plus 12 divided by 5 = 3,744.4
15 - 25 = -10
35 minus 10 = 25
-10 - 15 = -25
25 minus 15 is 10.
25 - 5 = 2020 - 5 = 1515 - 5 = 1010 - 5 = 55 - 5 = 0Therefore 5 can be subtracted 5 times from 25.
The Angstrom is a very small unit of linear measure. It so small that it is used in spectrometry to express the wavelength of light. It is 1 x 10-10 meters (or 10-10 m). That means that there are 1 x 1010 (or 1010) angstroms in just 1 meter. A kilometer (km) is 1000 meters, which is 103 meters, so there would be 1013 angstroms in a kilometer. (We add exponents: 1010 x 103 = 1010 + 3 = 1013.) As there are 1013 angstroms in a kilometer, there will be 10-13 kilometers in an angstrom. (We inverted to find that.) If you have 25 angstroms that you want to convert to kilometers, that's 25 x 10-13 kilometers in the 25 angstroms.
