How do you write an expression
(14x2)-9
-10
To write the expression "4 times the difference of 10 and 8 minus 3," you start by calculating the difference of 10 and 8, which is (10 - 8). Then, you multiply that difference by 4, giving you (4 \times (10 - 8)). Finally, you subtract 3 from that result, resulting in the expression (4 \times (10 - 8) - 3).

To write "5 subtracted from a quarter of s" as an expression, you can first express a quarter of s as s/4, and then subtract 5 from it. The expression would be s/4 - 5.

-- Write the two latitudes. Write a north latitude as a positive number, and a south one as a negative number. The calculation to come will be easier if you write the latitudes in the form of decimal degrees. You can obtain them from the numbers you have like this: Decimal degrees = (DEGREES) + (MINUTES/60) + ( SECONDS/3,600) -- On a blank sheet of paper, or in in the margin of a pre-used one, write one latitude underneath the other. -- Subtract. -- The number resulting from the subtraction is the difference between the original two latitudes.
Since there is no "equals" in the question, there cannot be a formula, only an expression.

(n-4)/5 Remember p.e.m.d.a.s. The parentheses signify which part of the expression to do first. They are very important. You get a different answer without them.
