Question

(1) |-9| + |-2|step by step explaination ​

Answer 1

Answer: 11

Step-by-step explanation:

|a|← this line on both sides of a no. is called modulus.

It represents magnitude i.e. whatever may be the sign we take or consider only the no.

for example-

|3| = 3    and     |-3| = 3

so, |-9| + |-2| = 9 + 2 = 11
