What is binary? What is binary?

Binary is a number system widely used in computing technology. Binary data is a number represented by 0 and 1. Its cardinal number is 2, carry rule is "every two into one", borrow rule is "borrow one when two add". There are four cases: 0 + 0 = 00 + 1 = 11 + 0 = 11 + 1 = 00, carry is 1

(10010) 2 △ 110) 2 + (10101) 2 △ 11) 2 binary operation (100100) 2 - (1011) 2 × (11) 2 + (11011) 2 binary operation

(10010) 2 △ 110) 2 + (10101) 2 △ 11) 2 binary operation
=（11）2+（111）2
=（1010）2
(100100) 2 - (1011) 2 × (11) 2 + (11011) 2 binary operation
=（100100）2-（100001）2+（11011）2
=（11)2+(11011)2
=（11110）2
