240+[8400]=8,640 First, we need to multiply x,s numbers to find x2. 1x2x3x4x5=120, x=120. So 120 times 2 equals 240, so we have 240+[ ? ]= ? Next, we need to find the total or the sum of this equation so 3x8x15x24= 8640. So our problem is just like this so far, 240+[ ? ]= 8640, so the final thing to find the missing value is to subtract 240 from 8640, so 8640-240= 8400. So the equation is 240+8400=8640. Hope this helps :)
