133 can be divided by 7, so it is not prime.
143 can be divided by 11, so it is not prime.
153 can be divided by 3, so it is not prime.
163 can only be divided by 1 and itself, so it is prime.
Adding and subtracting are used in Please excuse my dear aunt sally, which if u never heard of this the P is for parentesies, E is for exponents, M stands for multiplication, D stands for Division, A is for adding, and S is for subtraction.
Also u use it during order of operations
You can use it for solving for a variable.
Answer:
24.1 x 10^4 = 241000 .056 x 10^7 = 560000 507 x 10^-5 = 0.00507
Step-by-step explanation:
for scientific notation, all you need to do is start at the decimal point (or end of whole number) and move over the amount of spaces (the exponent) to the right. if it is a negative exponent, instead of moving to the right, you should move to the left.
for example : 500 x 10^3
when you start from the last zero and move to the right, you need to fill the space with three zeroes.
so 500 x 10^3 = 500,000.
You would have 3 liters. 3 liters is the same to 300 centiliters.
