-2 plus 5 equals +3
It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
a + c - b = 3 + 2 - 5 = 5 - 5 = 0
5-2=3n=3
2/5
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
If x=2, then 7x = 14 and if y=5 then 4y=20.
(5/2 + √17/2) ≈ 4.562, and(5/2 - √17/2) ≈ 0.438
9+5=14 divided by 7 equals 2
