i have lots of problems in solving maths can anyone give me tips to solve maths, is the maths hard ?

Depends on the type of math. I feel you though, as math is my worst subject. Do you tend to find it hard to focus when doing so? Maybe paying more attention could help you out. You could ask your friends or family for help. Asking for it can be hard, but it'll be worth it and will save time. Or, im pretty sure has tutoring, so check that out if you want. Math can be hard, especially if its common core, so i acsolutely feel you.

Moral of the story:

Common core math sucks.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
