Multiplication and division: Large Numbers

First, perform the multiplication: $34 \times 8 = 272$.

Next, perform the subtraction: $272 - 13 = 259$.

Finally, subtract 54: $259 - 54 = 205$.

First, perform the multiplication: $45 \times 7 = 315$.

Next, perform the subtraction: $315 - 25 = 290$.

Finally, subtract 50: $290 - 50 = 240$.

First, perform the multiplication: $35 \times 9 = 315$.

Next, perform the subtraction: $315 - 15 = 300$.

Finally, subtract 65: $300 - 65 = 235$.

First, perform the division: $48 \div 8 = 6$.

Next, perform the multiplication: $6 \times 3 = 18$.

Finally, perform the addition: $16 + 18 = 34$.

First, perform the division: $54 \div 3 = 18$.

Next, perform the subtraction: $75 - 18 = 57$.

Finally, perform the addition: $57 + 9 = 66$.

First, perform the division: $121 \div 11 = 11$.

Next, perform the multiplication: $7 \times 4 = 28$.

Finally, perform the addition: $11 + 28 = 39$.

First, perform the multiplication:$8 \times 4 = 32$.

Next, perform the division: $32 \div 2 = 16$.

Finally, perform the subtraction: $64 - 16 = 48$.

First, perform the division: $18 \div 6 = 3$.

Next, perform the multiplication: $3 \times 5 = 15$.

Finally, perform the addition: $90 + 15 = 105$.

According to the order of operations, we first put the multiplication exercise in parentheses to avoid confusion in the rest of the solution:

$(25\times6)-9-41=$

Let's solve the multiplication exercise first:

$150-9-41=$

Now let's solve the exercise from left to right:

$150-9=141$

$141-41=100$
