its 3
2
so if you add 1 to 1 its 2
-1
Two numbers that equal -2 are -3 and 1. When you add -3 and 1, you get -2. This is because -3 + 1 = -2.
-3+1
2
1+3 = 4 but 13 = 1
1 + i and 1 - i, where i is the imaginary number equal to the square root of -1
-2 - 2i and -2 + 2i where i is the imaginary square root of -1.
111, 2 and 1.
1/4 = 2/8 and so if you add 2/8 and 3/8 you have 4/8 which is 1/2 So asnwers: 1/2
20, 4 and 2 if you add them. 13, 2 and 1 if you multiply them.
