Answer 2

It looks like you've provided a series of mathematical expressions with different operations. Let's solve them step by step:

a) $450 \cdot 240 - 1200.45 - 4500 \cdot 12 + 5$

Perform operations from left to right according to the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

$= 108000 - 1200.45 - 54000 + 5$
$= 54004.55 - 54000$
$= 4.55$

b) $\frac{4750}{19} - 19 \cdot 13 \cdot 84 - 242$

$= 250 - 24732 - 242$
$= -24524$

c) $\frac{723600}{90} - 40 \cdot 201 + (1234.4321 - 1999) + 5$

$= 8040 - 8040 + 1234.4321 - 1999 + 5$
$= 240.4321 - 764$
$= -523.5679$

r) $1998 - 1999 - 19982 - 1993 \cdot 20 + 70 \cdot 2579$

$= -1 - 19982 - 39860 + 51400$
$= -8479$
