Question

Solve a-15=25. State which Equildean axiom do you use here?

Answer 1

$$\begin{gathered} a-15=25 \\ \mathrm{Using}\mathrm{Euclid}\text{'}\mathrm{s}\mathrm{axiom}, \\ \mathrm{if}\mathrm{equals}\mathrm{are}\mathrm{added}\mathrm{to}\mathrm{equals},\mathrm{then}\mathrm{the}\mathrm{remainders}\mathrm{are}\mathrm{equal}. \\ \Rightarrow a-15+15=25+15 \\ \Rightarrow \mathrm{a}=40\left(\mathrm{answer}\right) \end{gathered}$$
