To depend confidently on and put trust in do actually convey the correct meaning when properly understood.
When you rely on something that means you place the successful outcome of your endeavor on the proper performance of that thing.
In other words, if the thing that you rely on fails, then you cannot complete your mission successfully.
You may use something without relying on it if you have a contingency plan that allows you to complete your objective by other, perhaps less satisfactory, means.
If I rely on you to get me to the party and you forget to pick me up, then I never get to the party. If I ask you for a ride but also know that I can call my brother if you fail to show up, even though I might get to the party a little late if I have to do that, then I am not relying on you to get there.
I may be relying on you to get me there on time.
Going back to the dictionary definitions:
IF I depend confidently in you to get me to the party that means my dependence in you is complete and if you fail then I fail. Likewise if I trust you to get me to the party and you betray my trust then again I don't make it.
If I don't trust you or don't want to depend on you, i.e., I don't want to rely on you, then I make backup plans.

DEFINITIONS:
OPERATORS : operators are symbols that allow the user to instruct the computer to preform
a certain mathematical or logical operation
OPERANDS : operands are constants, variables, objects, functions to be operated on by the
operator
TIP To understand many of the terms used in computer science and mathematics better, it is
helpful to understand the following suffixes that apply to many of these terms.
Suffix Definition In Context
-and : the subject that is to be dealt with in a specified way
-tor, -or, -er : the agent: that takes an active role in or produces a specific effect
OPERATORS:
Examples
Logical operators :
plus sign [+], hyphen-minus [-], x or asterisk [*], ÷ or forward-slash [/], caret [^],
backslash [\], vertical line [|]
Comparative operators :
lesser-than sign [<], greater-than sign [>], equal sign [=], or other symbols.
Includes definer words such as NOT, AND, OR, etc.
In Computer Science:
• asterisk [*] replaces 'x' for multiplication
• forward-slash [/] replaces the typical obelus (÷), fraction bar, Semi-colon, or
long-division (division bracket and vinculum) often used in written mathematics to
represent division and/or fractions
• caret [^] replaces the superscript representation of exponents in written mathematics.
e.g. A^B is equivalent to A<sup>B</sup>
• because of the impracticality of using a large set of symbols that traditional written
math incorporates, logical and comparative operators are typically replaced with
definer words, which vary depending on the programming language.
e.g. NOT is equivalent to the not-equal-to symbol [≠] in Visual Basic
Note: order of operation qualifiers and functions are not discussed here
EXPRESSIONS and OPERANDS (unambiguous):
additive expression
addend summand sum
| | |
[subject][agent][result]
| | |
A + B = X
in the additive expression, the left operand is the subject and is called an 'addend', while
the right operand is the agent called a 'summand'. The result is called a 'sum'
• A and B (or all numbers to be added together) are referred to as 'addends' generally
subtractive expression
minuend subtrahend difference
| | |
[subject] [agent] [result]
| | |
A — B = X
in the subtractive expression, the left operand is the subject called a 'minuend', the right
operand is the agent called a 'subtrahend'. The result is called the 'difference'
divisional expression
dividend divisor quotient
| | |
[subject] [agent] [result]
| | |
A ÷ B = X
in the divisional expression, the left operand [subject] is called 'dividend', the right
operand [agent] is called 'divisor'. The result is called 'quotient'
multiplicative expression
multiplicand multiplier product
| | |
[subject] [agent] [result]
| | |
A x B = X
in the multiplicative expression, the left operand [subject] is called 'multiplicand', the
right operand [agent] is called 'multiplier'. The result is called 'product'
• A and B (or all numbers being multiplied together) are also called 'factors' generally
exponential expression
base exponent power
| | |
[subject] [agent] [result]
| | |
A ^ B = X
in the exponential expression, the left operand [subject] is called 'base', the right
operand [agent] is called 'exponent'. The result is called 'power'
• B (the exponent) is sometimes called the 'index'. It is also often referred to as
the 'power' erroneously. Only the result is correctly named 'power'
• an exponential expression is also called an 'exponentiation'
(like multiplication, addition, division)
comparative expression
comparand comparator result
| | |
[subject] [agent] [result]
| | |
A <=> B = X
in the comparative expression, the left operand [subject] is called 'comparand', the
right operand [agent] is called 'comparator'. The result is called 'result'
• in a comparative expression, all operands are expressions in themselves. The result is
obtained by comparing these expressions to each other.
• the operands (expressions) of a comparative do not have to be numbers, but can be strings,
objects or other values and functions. Every comparative result equates to binary
values TRUE or FALSE. (e.g. does false equal true = false, does 3 equal 4 = false)
• the end result typically equates to a Boolean value. In computer science, comparative
operators may include AND, OR, XOR, NOT or a combination of these and the
"<, >, =" symbols; or other symbols and definer words as well.
e.g. JavaScript '==' means equal-to
• in all of the example expressions above, X (the result) is a comparative expression to AB
that invokes the calculation of the value that results to TRUE of the comparative.
If we put 'Y = " in front of them, then Y equals the binary comparative of AB=X,
X being an expression in form of a value that the comparative AB=X compares whether is
TRUE or FALSE.
Best Answer
If you unpack the word "urgent" then it comes across a bit better.
"I'm not in a hurry to do something" or "I'm in no rush to do something"
