The numbers in the brackets are equal to 100 The key is how 9 comes from. It's better to have a formula

9+9=18
9-9=0
9*9=81
9\9=1
18+0+81+1=100

100 minus ones add up to minus 100,

Yes
100*（-1）=-100

The multiplication of those two numbers is - 1700 and the sum is 65
It's an integer, or you can help me solve the equation x2 + 65x = 1700

85,-20

Which two numbers add up to - 35 and multiply by 264?

（－24）×（－11）＝264
（－24）＋（－11）＝－35

Which two numbers add up to 7 and multiply by 3

Let one of the numbers be x, then the other is 7-x
Then x (7-x) = 3
The results show that x ^ 2-7x + 3 = 0
7±√37
x=--------
two

The sum of two numbers is equal to the multiplication of the two numbers
For example, 2 * 2 = 2 + 2

A × a = a + AA ^ 2 = 2A (a ^ 2) / a = 2A = 2A × B = a + bab = a + Ba = A / B + 1a-a / b = 1a (1-1 / b) = 1A = 1 / (1-1 / b) a = B / (B-1) choose any number (except 0 and 1) when B is brought into the above formula, calculate the value of A. A ^ 2 = 2AA ^ 2-2a = 0A = [2 ± √ (4-0)] 2 = (2 ± √ 4) △ 2 = (2 ± 2) △ 2 = 1 ± 1A1 = 2A2 = 0

What numbers add up to three and multiply by one

Let two numbers be a and B
Then a + B = 3, ab = 1
So (a-b) ^ 2 = (a + b) ^ 2-4ab = 5
A-B = root 5
So a = 3-radical 5 / 2, B = 3 + radical 5 / 2

The multiplication of two numbers equals 9379500, and the addition equals the negative 6250

Two numbers are equations
The solution of x ^ 2 + 6250x + 9379500 = 0
x=[-6250±√（6250^2-4*9379500）]/2
=(-6250±√1544500)/2
=(-6250±1242.779144)/2
x1=-3746.39
x2=-2503.61
Answer:

Multiplication of two numbers equals 1100, and addition equals minus 150

a*b=1100
a+b=-150
a=-30,b=-120

There are three numerators, which can form six different three digit numbers. The sum of them is equal to 3330. What is the largest one?

Three numbers a, B, C
A, B and C appear twice in the hundreds, tens and ones respectively
That is, 2A * (100 + 10 + 1) + 2B * (100 + 10 + 1) + 2C * (100 + 10 + 1) = 3330
a+b+c=15
The maximum of three numbers can be 9, the minimum cannot be 0, and it is 1
15-9-1 = 5, take 5 in the middle
The biggest one is 951
