Answer:
- multiplying a multi-digit number by itself several times (finding the power of a number)
- finding a square root
- statistical calculations
Step-by-step explanation:
We don't know what your introduction tells you, but the above-listed operations are ones I choose to use a calculator for. I also use a calculator for ordinary arithmetic, such as division by numbers with 2 digits or more. (It is simply faster and requires no scratch paper.)
If statistical calculations are not done with a calculator, they at least require the availability of suitable tables.
___
All of these operations can be done by hand without a calculator, and were in times passed. Lifetimes of effort were involved in generating some of the original math tables for statistics, trig, logarithms, and other functions readily evaluated using a modern calculator.
Answer:
8
Step-by-step explanation:
416/52 = 8
i think the answer is 37 because if their are 22 boxes left 1/2 was burnt you want to undo to the problem so 22 times 2 is 44 - 7 since we want to go back a week and the answer is 37
Step-by-step explanation:
use substitution method so it will now look like
8x + 5(-4x) = 24
8x + (-20x) = 24
-12x = 24 (divide both sides by 12)
-x = 2 (multiply both sides by negative 1)
x = -2
substitute to find y
y= -4(-2)
=8
