I think this is correct:
10 x 9 = 90
90 x 8 = 720
720 x 7 = 5040
5040 x 6 = 30240
30240 x 5 = 151200
152,200 x 4 = 608,800
608,800 x 3 = 1,826,400
1,826,400 x 2 = 3,652,800
3,652,800 x 1 = 3,652,800
I hope it helps.

(10 x9 = 90) (8 x7 = 56) (6 x 5 = 30) (4 x 3 = 12) (2 x 1 = 2)
90 x 56 = 5040
30 x 12 x 2 = 720
5040 x 720 = 3628800
10x9x8x7x6x5x4x3x2x1 = 3628800

are you really looking for the sum or the product?
it looks like you're looking for a product.
sum is +
product is x
the answer is 55 becuz you're looking for a sum.
10+9 = 19
19 + 8 = 27
27 + 7 = 34
34 + 6 = 40
40 + 5 = 45
45 + 4 = 49
49 + 3 = 52
52 + 2 = 54
54 + 1 = 55
i guess i should get ten for PAYING ATTENTION to the question. lol.

Hey, I'm not gonna do your homework for you, but did you know there's a name for this kind of sum?
If you want to multiply something by every whole number (integer) between that number and 1, it's called finding the 'factorial' of a number.
e.g. 3x2x1 = 3 factorial. This has the coolest mathematical symbol of all. It's written:
3!
whereas your question could be written:
10!
Which is really fun. Anyway, quit wasting time, get pen and paper and do it one stage at a time. If you must use a calculator, do it afterwards, or you won't learn anything.

Sigh. How do schools expect kids to learn ANYTHING nowadays?

1. Right side is 29 cm; the length of the sloping side to the nearest centimetre is 29 cm 2. Yes, because √(5^2+12^2) = 13 3. Ann was correct, because √(10^2+11^2) = 14.866 4. Area of the triangle =.62.353824 sq. cm
