What is deduction in finance math

In mathematical logic, a deduction theorem is a meta theorem that justifies doing conditional proofs — to prove an implication A → B, assume A as a hypothesis and then proceed to derive B — in systems that do not have an explicit inference rule for this.

Step-by-step explanation:

For example to solve 2x = 6 for x we divide both sides by 2 to get 2x/2 = 6/2 or x = 3. What we know or assume is that 2x = 6 and that you can divide both sides of an equation by any non-zero number and the equation is still valid. From these two facts we deduce that x = 3. This is the type of reasoning we use in almost every step in a mathematical argument.

sorry not sure

step-by-step explanation:

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km
