A palindrome number is a number that is the same backwards as is forwards, like 123321.

What is the largest 6 digit palindrome number that is a multiple of 18?

focused on the left side of palindrome, ex: 286 -> 286682. started from 899, and changed digits until i got them to add up to a multiple of 9 (9's divisibility rule and one of 18's factors), ex: 3+6=9, 2+8+1=9 since 18 is even, palindrome should to be even too, which is why i set first digit to 8.

899,898,897,896...891,891198

OK, I still want you to prove that it is 5!

thats incorrect, you might've done the PEMDAS steps wrong
P-Parentheses
E-Exponents
MD- Multiply or Divide
AS- Add or Subtract

if you're saying its 5, then you subtracted first instead of multiplying, which doesn't follow the order


I never said it wasn't 120, I said it was also 5!

The ! symbol in math refers to factorial notation. The factorial of a number is equal to the product of itself and every positive integer before it. So 3! would be 3x2x1=6 and 5! is 5x4x3x2x1=120.

Solve this:

∫(2x² - 3x + 1) dx + Σ_{k=1}^3 (k² - 2) = ln(e^x) + |x - 2|

Good luck.

You don't need a symbol for it to be multiplication.

Write proof:

Given: Quadrilateral WATR, with line segment WA congruent to line segment RT and line segment WR congruent to line segment AT, with diagonal WT.

Show: WATR is a parallelogram.

No he doesnt mean that it’s unnecessary to have a multiplication symbol when theres numbers in brackets after a number

82x + 9(25x) - 540 = 212x + 45(105) + 68x
82x + 225x - 540 = 212x + 4725 + 68x
307x - 540 = 280x + 4725
27x - 540 = 4725
27x = 5265
x = 195
