Correct! How did you get this?
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

Prove: The answer is 5!
PEMDAS, multiply first, then subtract.
230-220(1/2)
230-110
120
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!
Answer:
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.
∫(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.

Bro my homework:
Construct Square SQRE with the given diagonal SR.
and...
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

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

What is x
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
