Internet Layer: This a 5 part quest please explain the math clearly

An ISP has a 127.3.0.0/16 IP address.
14. Customer A is given a 127.3.0.0/24 group of IP addresses. How many
addresses do they get
15. What is the range of IP addresses they get? (E.g. if A got 2, the answer
might be 127.3.0.0-127.3.0.1)
16. Customer B is given another /24 block immediately after Customer A's
block. What is the CIDR notation for their block?
17. Customer A and Customer B are physically near each other. If we want a
way to refer to their combined block, what is a single CIDR notation for
both sets of IP addresses?
18. What is the subnet mask for this new merged subnet?
