Yes, it is the same for the same weight. Both are considered 'oversized' mail or 'flats' and cost more than a normal business envelope. the current rate would be 88 cents for the first ounce and 17 cents for each additional ounce.
11, as 11-12-(-12) is the same as 11 + (-12+12), and -12 +12 cancels out to zero, leaving you with 11 + 0 = 11.
Division is the same thing as multiplication. To find the answer, you multiply 12 and 11, which equals 132. (12 x 11 = 132) 132/12=11 OR 132 ÷ 12 = 11 same thing as 12 x 11 = 132
11 increased by 12 is the same as 11 plus 12 so the answer is 23
The reciprocal of 12/11 is 11/12.
11/12-3/4= 11/12 and 3/4 have different denominators. So we multiply 4 by 3 to get the denominators the same. If we multiply 4 by 3, we should also multiply 3 by 3. 11/12-9/12=2/12 If it asks us it in the simplest form, 2/12 find the LCM, 2. And divide it by 2, 2/12=1/6.
You will need postage for the weight of the envelope (probably 2 ounces, for 4 sheets of paper in a 10x13 envelope), plus a surcharge for the size of the envelope. Best guess: $1.19 for first class mail within the United States, as of Feb. 2014.

Currently (12/19/2009) 44 cents in the US, if the envelope size does not exceed 11-1/2 inches long, by 6-1/8 inches in height.
The number of stamps needed for an envelope depends on the weight and destination. The weight limit for a standard USPS First-Class Mail envelope is 3.5 ounces. For an envelope weighing 12 lbs, you would need to use a different shipping method, such as USPS Priority Mail or USPS Priority Mail Express. The specific number of stamps required can be calculated using the USPS postage rate calculator or by visiting your local post office.
11, as 11-12-(-12) is the same as 11 + (-12+12), and -12 +12 cancels out to zero, leaving you with 11 + 0 = 11.
That all depends on how much is in it. It goes by weight. See the U.S. domestic postage website at the link below. Anyway, it's not about "how many stamps" but "how much postage." Stamps come in denominations from 1 cent on up.
Priority Mail flat rate envelopes cost US$5.75 in postage. With standard 49 cent stamps, it would take 12 stamps to cover the postage.

In the UK the Royal Mail charge £1.10 second class, £1.20 First Class. Overseas delivery will be higher.
