Adding a negative number has the same effect as subtracting a positive number. In this instance:
10 + (-7) = 10 - 7 = 3
7 + 10 = 17
17
pH 3 is 10^-3 and pH 7 is 10^-7 which is the same as saying 0.001/0.0000001 which equals 10,000!
6.15
In a neutral solution, the H plus is equal to OH-. The pH level in such a solution is usually at 7.
The pH is 6,15.
6 pounds 3 ounces.
-7 plus 10 is the same as 10 minus 7, which is 3.
10 + 7 + 3 = 20
7
23+7+10=40
7 + 90 / 9 + 10 + 42 - 7 7 + 10 + 10 + 16 - 7 36
7 over 10 plus 7 over 10 is 14 over 10 or 1.4
7+10+(-6x)=17-6x
(-10) + (-7) + (-14) = -31
7+3+10 = 20
-7 + 10 = +3
7/10 + 7/10 = 7/5
4-7+10=7
