More properly stated: negative 3 minus negative 4 or [(-3)-(-4)]
(-3) - (-4) = 1
because - (-4) = + 4
- 3 - 4 = ? or - 3 + (-4) = ?- 3 - 4 = ?- 3 - 4 = - 7Answer = - 7Minus and to Subtract are techincally the same.- 3 - 4 = - 3 + (-4)
4
Positive 3 plus negative 5 minus negative 2 minus positive 4 is equal to -4.
1/4 = 4/16 - multiply top and bottom by 4. Now both numbers are 16ths so just subtract 4 from 7 and the answer is 3, (3/16) I think your calculation must be 7/16 minus 1/4 because you can't subtract 7 from 4.
plus times plus = plus minus times plus = minus plus times minus = minus minus times minus = plus so when you subtract a number it is the same as adding its negative; for example 7 - 4 = 3 7 + (1)(-4) = 3
