Order of operation… Math operators in Excel

The math operators in Excel have an order of operation, just like in regular math. The order of operation is the order in which they’re processed when multiple operators appear in the same formula. Here are the rules that determine the order:

1. Any operations that are in parentheses, from left to right
2. Exponentiation (^)
3. Multiplication (*) and division (/)
4. Addition (+) and subtraction (-)

Parentheses override everything and go first. So, if you need to execute an operation out of the normal order, you place it in parentheses.

For example, suppose you have this formula:

=5+16/4^2

The order of operation looks like this:

1. The exponentiation (4^2 equals 16)
2. The division (16/16 equals 1)
3. The addition (5+1 equals 6)

The result of the formula is 6.

If you wanted the addition to occur first, you could put parentheses around the addition portion of the equation, like this:

=(5+16)/4^2

This time, the order of operation looks like this:

1. The part in parentheses (5+16 equals 21)
2. The exponentiation (4^2 equals 16)
3. The division (21/16 equals 1.3125)

The result of this formula is 1.3125.

If you wanted to perform the exponentiation last, you could add another set of parentheses, like this:

=((5+16)/4)^2

Now the order is this:

1. The inner parentheses (5+16 equals 21)
2. The outer parentheses (21/4 equals 5.25)
3. The exponentiation (5.25^2 equals 27.5625)

The result of this formula is 27.5625.

If you left off the inner set of parentheses and wrote it like this:

=(5+16/4)^2

The order would be as follows:

1. The division, because it’s the highest-ranking operation inside the parentheses (16/4 equals 4)
2. The rest of the parenthetical operations (5+4 equals 9)
3. The exponent (9^2 equals 81)

The result of this formula is 81.

If you would like assistance completing this template, please do
not hesitate to contact ARIN’s Registration Services Help Desk
at +1 (703) 227-0660. We’ll be glad to help you!

TEMPLATE INSTRUCTIONS:

Please copy and paste the text-based template into the body of an
e-mail and send to hostmaster@arin.net with the subject line, “NETWORK
MODIFICATION”.

Please ensure your e-mail client sends ARIN the message as plain
ASCII text, not as HTML.

Please do not attach the template.

IMPORTANT NOTE: Do not remove or modify the template header, i.e.
the line beginning with “Template:” or the footer, i.e. “END OF
TEMPLATE”. Both are required for processing.

01. This template allows you to modify information for an existing
network, remove a downstream network, or return a network
to ARIN. The registration action is required. Valid values are:
M for Modify
R for Remove/Return

02. Indicate the network to be modified or returned. Valid values
are:
10.0.0.0/24
10.0.0.0 – 10.0.0.255

You cannot modify or return multiple discontiguous networks
with this template. Please submit a separate Network Modification
template for each distinct contiguous network registration.

03. If you do not wish to modify the network name, this field should
be left blank. If you wish to modify the network name, supply a
short name consisting of a combination of up to 50 letters and/or
numbers. You may use a dash (-) as part of the network name, but
no other special characters, such as periods or underscores.

04. Provide fully-qualified host names for the servers that will be
providing in-addr.arpa name services. DO NOT LIST IP ADDRESSES.

Networks should provide at least two (but not more than
thirteen) distinct nameservers for providing address-to-name
mapping for hosts in the network. To specify more than two,
duplicate field 04. for each additional server. Do not list
multiple servers on a single line.

05. Indicate the ARIN POC handle of a contact responsible for the
technical aspects of maintaining the IP address space. The
technical POC may make modifications to the allocated block.

Please note your Org ID already has a Technical POC which will,
by default, appear on the resource registration record.

06. Indicate the ARIN POC handle of a contact responsible for
handling operational aspects of the acceptable or appropriate
uses of the allocated network. The abuse POC may not make
modifications to the allocated network registration.

Please note your Org ID may already have an Abuse POC which will,
by default, appear on the resource registration record.

07. Indicate the ARIN POC handle for your NOC. The NOC POC may
not make modifications to the allocated network registration.

Please note your Org ID may already have an NOC POC which will,
by default, appear on the resource registration record.

08. If there are any comments you would like publicly displayed in
ARIN WHOIS regarding this registration, detail them here.

Suggested comments are:
Public Comments: http://www.example.net
Public Comments: Standard NOC hours are 7am to 11pm EST
