When a number in the form ab=1, the left side of the equation must be in one of the forms:a0 anda≠0,1ANYNUMBERor(−1)EVENNUMBER Case l:1:b=0⇒x=−2 so a=−7and(−7)0=1 Case Il:a=1⇒x=6so b=8and(I)8=1 Case Ill:a=−1⇒x=4so b=6and(−1)6...
For each problem, find the sum of the two numbers to the left of the equal sign. You may use simple counting or a number line. The answer to 3 + 4 = 7 which is correct. The answer to 10 + 18 = 28 which is correct. The answer to 7 + 6 = 13. The equation above shows 7 ...
In the equation: n is the number of terms; a is the first term; and l is the last term. What is the sum of 1 to N? 1 + 2 + 3 + ... + N = N(N + 1) / 2 We can use this formula to find the sum of the first N natural numbers. This formula results from the sum ...
Use the lumpsum calculator to estimate the final balance or compute any lumpsum-related factors, for example, the required rate of return or the necessary periods to reach a certain final balance.
sumof(numbers)=first(numbers)+sumof(rest(numbers))sumof(numbers)=first(numbers)+sumof(rest(numbers)) In this equation first(numbers)first(numbers) returns the first element of the list and rest(numbers)rest(numbers) returns a list of everything but the first element. This is ...
