Question

Why does 5 plus 5 equal 10 please explain why cause "5" and "10" are written differently-

Answer 1

Its because the mathematical principle .

`\\ \sf\bull\dashrightarrow 5+5=10`

• Two 5s are added up to give 10.
• So 5 is written alone

Note

• (-)(-)=(+)
• (+)(-)=(-)
• (-)(+)=(-)
• (+)(+)=(+)
