One in three plus one in two minus one in three plus one in two equals

One in three plus one in two minus one in three plus one in two equals

1/3+1/2-1/3+1/2=1

Why is it equal to [A-4] [a + 2] = 0

A-178; - 2a-8 = 0 split the first term and the last term into a-178; = a * a - 8 = - 4 * 2 by cross multiplication (this is to be tried), and then write a-4a 2 cross multiplication-4a + 2A = - 2A is exactly equal to the middle term. A-178; - 2a-8 = (A-4) (a + 2) = 0 is suitable for factorization problems with only three terms

536 △ 536 and 536 / 537 need complete calculation process and solution

536 △ 536 and 536 / 537
=536÷(536＋536/537)
=536÷536÷(1+1/537)
=1÷538/537
=537/538

a. If B is opposite to each other and C and D are reciprocal to each other, what is (a + B + 1) (a △ b) - 2004cd equal to
It's not a problem, but I've caught a cold recently, and I have a headache when I think about it

Because a and B are opposite numbers,
So (a + b) = 0, (a △ b) = - 1
Because C and D are reciprocal, CD = 1
So (a + B + 1) (a △ b) - 2004cd
=（0+1）（-1）-2004*1
=-2005
