Please help me understand these difference in following "audit" terms

Compare means for example, compare last year’s electricity expense to this year’s.

Reconcile means bring into agreement or explain differences. Eg reconcile bank balance to cash book balance.

Agee is similar to match eg match/agree goods received notes to orders.

Review is a relatively brief look at something.

Recalculate means repeat a calculation; reperform could mean repeat a calculation but can be wider eg repeat a process such as a bank reconciliation.
