How does a calculator multiply?
Calculators (and computers) combine inputs using electronic components called logic gates. There are several types of logic gates: AND, OR, NOT and XOR (exclusive OR). Together, the logic gates enable circuits to add, subtract, multiply and divide the numbers sent to them by transistors.
Can calculators be wrong?
Yes, calculators can be wrong. They are nothing but simple computers and as such are only as good as their coding and will always have some limitations involving for instance rounding. Some errors can be avoided by paying attention to how you enter a problem if you are aware of the flaw in the coding.
Do calculators follow Bodmas?
BODMAS or BIDMAS must also be used when using a calculator. Scientific calculators automatically apply the operations in the correct order, however extra brackets may be required.
What is the formula for multiplying by 2 and 8?
Multiplying by 8 is the same as multiplying by 2, multiplying by 2 and multiplying by 2 again. This is because 8 = 2 × 2 × 2. We double a number three times to multiply it by 8.
How do you multiply 2 and 4 together?
Multiplying by 4 is the same as multiplying by 2 and then by 2 again. This is because 4 = 2 × 2. Multiplying a number by 2 is known as doubling it. To double a number we just add it to itself. To multiply a number by 4, we double it and double it again.
What is the difference between multiplying by 2 and doubling?
Multiplying a number by 2 is known as doubling it. To double a number we just add it to itself. To multiply a number by 4, we double it and double it again. 5 doubled is 5 + 5, which equals 10. We double again to get 10 + 10, which is 20. 5 × 4 = 20. Multiplying by 8 is the same as multiplying by 2, multiplying by 2 and multiplying by 2 again.
What is the value of multiplying by 4?
