3/4 is equal to 6/8
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
1+3 = 4 but 13 = 1
6 - 3 x 2 + 4 = 4

If you add them, they equal 57.
There is no answer to this. The factors of 15 are 1, 3, 5 and 15. The only numbers that add up to four are 1+3, 4+0 and 2+2.
The factor pairs of 4 are (4,1) and (2,2). Neither of them add up to 3. If your question was about negative 4, you could use 4 and -1.

If you mean ' "When" do you add exponents? ' then the answer is when the same base of equal or different exponents is multiplied. in other words, when you hav "3 exponent 3 times 4 exponent 5 " you can't add the exponents because the bases (3 and 4) aren't the same.
