then 4 plus 3 equals 28 and 3 plus 3 equals 18 and 7 plus 5 equals 84 .... its easy you just have to multiply the answer with the first number.. for example : 2 plus 3 equals 5 but when you multiply the answer with the first number (2) it becomes equals 10, and so on the others..
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.
It equals 24.
7+2+5= 14 35 42
