How do you spell pH?
the definition of pH is a measurement of bases and acids. potential of hydrogen ion concentration potential of hydrogen ion concentration Every water solution contains H+ ions. Their concentration is one of the most important parameters describing solution properties. Concentrations of H+ can change in a very wide range, it can be 10 M as well as 10-15 M. Such numbers are inconvenient to use so to simplify things Danish biochemist Søren Sørensen developed in 1909 the pH scale and introduced pH definition - minus logarithm base 10 of [H+]:

Why pH 2 is stronger then pH 3?
pH is defined as -log10[H+] it is a logarithmic scale, each gradation is a factor of 10. And just for good measure the minus sign tells you it runs "backwards" So for HCl pH 1 0.1 M pH 2 0.01M pH3 0.001M so pH 2 has 10X concentration of acid of pH2

Do two plus signs make a minus?
In addition and subtraction, if the plus sign is larger than the minus sign, then it's a plus. For example: +10 minus -20 = -10 If the plus sign is smaller than the minus sign, the answer will be a minus. For example: -10 minus + 20 = -10 In multiplication, if you have 2 plus signs, the answer will be a plus sign. If you have 2 minus signs, the answer will be a plus sign then, too. But if you have a plus and a minus sign, then the answer will be a minus. For example: +5 x + 2 = +10 -5 x - 2 = +10 -5 x +2 = -10

Why is there 2 minus signs at the start of a Trim Excel formula?
All functions in Excel start with the = sign. So you may be mistaking that for two minus signs. A minus sign will have no impact on an TRIM function as it is a text function.All functions in Excel start with the = sign. So you may be mistaking that for two minus signs.
