How do you subtract a negative number from a negative number?
It´s like adding them. You pretend that the second number is a positive number and then you add the two numbers together. For example: (-7) - (-2) = -7 + 2 = -5 (-2) - (-7) = -2 + 7 = 5

What are the factors and prime factors of 350?
Its prime factorisation is:2 x 5 x 5 x 7 = 350 which can be written in index form (in other words, using exponents) as 2 x 52 x 7.In addition it has composite factors, which are found by multiplying combinations of these prime factors, and so we obtain this list:The 12 factors of 350 are 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, and 350If you write 350 = 2 x 52 x 7 = 21 x 52 x 71 then 350 will have (1+1)(2+1)(1+1) = 12 factors, because any factor of 350 consists of a product of (0 or 1) 2's, (0, 1, or 2) 5's and (0 or 1) 7's. So these are all of 12 of them.You can write (1+2)(1+5+25)(1+7) and expand this out to see all the factors (added), or evaluate it to get the sum of the factors of 350 is 3 x 31 x 8 = 744.The factor pairs of 350 are 1 x 350, 2 x 175, 5 x 70, 7 x 50, 10 x 35, and 14 x 25.The proper factors of 350 are 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, and 175, orif the definition you are using excludes 1, they are 2, 5, 7, 10, 14, 25, 35, 50, 70, and 175.The 3 distinct prime factors of 350 are 2, 5, and 7.1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350

What is the LCM of 189 and 75?
4725.189 = 3*63 = 3*3*21 = 3*3*3*7.75 = 3*25 = 3*5*5.The LCM needs 3 3's, 2 5's and a 7. ... (Leave out the 3 from 75 since there are already 3's in 189.)LCM = 3*3*3*5*5*7 = 27*25*7 = 675*7 = 4725.
What is the LCM of 210 and 450?
Start by factoring both numbers into primes: 210 = 2*3*5*7 450= 2*3*3*5*5 What's the shortest list that includes all the factors of both numbers? One 2, two 3's, two 5's, one 7 That's the recipe for lcm in this problem. lcm = 2*3*3*5*5*7 = 3150
What is the LCM of 35 245 175?
The LCM is 1,225Start by factoring all the numbers into primes: 35 = 5*7245 = 5*7*7175 = 5*5*7To encompass all 3 sets of factors, the LCD must contain two 5's and two 7's.LCD = 5*5*7*7 = 25*49 = 1225
