Multiplication is a simple way of adding
For example 6x8 is the same as 8+8+8+8+8+8
Any number multiplied by 1 is itself E.g 4x1 = 4
Multiplying by 2 is just doubling
Multiplying by 10 is adding a 0 to the original number
If it is a big number that you do not know how to multiply mentally split it up
E.g 17x13
Split 13 into 10 and 3
17x10= 170
17x3= 51
Then add these numbers
221
If you ever get stuck, use the long method, add them instead, you will get to the right answer but it will take longer
Dividing is not as simple
Like multiplication dividing by one will leave you with the same answer
Dividing by two means you half the number, which may give you a decimal
Bigger numbers are trickier, and you may be allowed to use a calculator for numbers

Answer:
3 hours
Step-by-step explanation:
24/7 = 3.42 hours and rounded that will be 3 hours
Okay, we can round each number to the nearest whole.
37.2 + 2583
Round 37.2
<span>If
the number after the decimal point is 5 or more, we round up, but if it’s 4 or
less, we round down.
</span>
The number is 2 so we round down to 37.
Now we add 37 + 2583, which equals 2620.
18.256 - 5.71
Again, look at the numbers after the decimal point.
For 18, it's 2, so we round down to 18. For 5, it's 7 so we round up to 6.
So we have:
18 - 6
Subtract:
12
-9.916 + 12.4
Again, look at the numbers after the decimal point.
For -9, it's 9, so we round up to -10, for 12, it's 4, so we round down to 12.
So we have:
-9 + 12
Add:
3
