Explanation:

Step1: Calculate product of 91 and 548

$91\times548=(90 + 1)\times548=90\times548+1\times548=90\times(500 + 40+8)+548=(90\times500)+(90\times40)+(90\times8)+548 = 45000+3600 + 720+548=49868$

Step2: Calculate quotient of 1106 divided by 7

$1106\div7 = 158$

Step3: Calculate difference of 16.98 and 11.08

$16.98−11.08 = 5.9$

Step4: Compare 10.001 and 10.01

Since $10.001<10.01$, the symbol is $<$

Step5: Compare 20.10 and 20.1

$20.10 = 20.1$, the symbol is $=$

Step6: Write expressions with solution 4

$8\div2=4$, $16 - 12=4$

Step7: Find factors of 83

The factors of 83 are 1 and 83. Since it has only two factors, 83 is prime.

Step8: Order numbers

$74.01>73.50>73.05$

Step9: Value of underlined digit in 5678.321

The underlined digit 1 is in the thousand - ths place, so its value is 0.001

Step10: Calculate products

$33\times10 = 330$, $33\times1=33$, $33\times0.1 = 3.3$, $33\times0.01=0.33$

Step11: Calculate sums

$73.1+10 = 83.1$, $73.1 + 10^{2}=73.1+100 = 173.1$, $73.1+10^{3}=73.1 + 1000=1073.1$
