No they used to be called S & S :)
n+m
Where m and n are statements m n is called the _____ of m and n.
The mass of one specific isotope, called the mass number, is the total number of protons plus neutrons. M = P + NTherefore, for atomic number P, you would take the mass number minus the neutrons: P = M - N.
one third of a number m
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
Concentration is a measure of mass in a certain volume, its called m/v concentration. (Others: m/m concentration, v/v concentration)
Find the square root of M.
The number "m" in Roman numerals represents the value 1000.
That means if you multiply 3 and m together, you will get the number. Suppose the number is 24. Then you know that m = 8.
m/2
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
