it goes on forever. It cannot accurately be written out in full, so it is most simply expressed as the surd √5. △Not a surd The square root of 4 is not a surd. It is the number 2, a whole, or rational number. Simplifying surds Some surds can be made simpler by taking out factors that can be written as whole numbers. A few simple rules can help with this. ▷ Square roots A square root is the number that, when multiplied by itself, gives the number inside the root. a × a = a 3× 3 = 3 multiply the

not already have one. ▷ Move the decimal point Move along the number and count how many places the decimal point must move to form a number between 1 and 10. ▷ Write as standard form The number between 1 and 10 is multiplied by 10, and the small number, the “power” of 10, is found by counting how many places the decimal point moved to create the first number. 1,230,000 add decimal point 3 2 1 0.0006 1 2 3 4 1,230,000. 0.0006 the decimal point moves 4 places to the right the decimal point

the answer, 7, after a decimal point. 4 multiply 8 times 7 to get 56 first remainder is 4 Work out the first remainder by multiplying 8 by 7 and subtracting this from 60. The answer is 4. 0.75 8 6.0 0 0 60 56 40 8 goes into 40 exactly 5 times bring down a 0 divide 40 by 8 Bring down a zero to join the 4 and divide the number by 8. It goes exactly 5 times, so put a 5 above the line. LOOKING CLOSER Decimals that do not end Sometimes the answer to a division can be a decimal number that

a scale, then draw the reach of each transmitter. An appropriate scale for this example is 1cm : 50km. everyone inside, and on, the locus can receive station A B this area is where signals from transmitters cross over B using the scale, 3cm represents 150km A 3c m this arc represents a section of the locus of all points that are 150km away from transmitter A Construct the reception area for radio station A. Draw the locus of a point that is always 150km from station A. The scale gives

CLOSER DIVISION 23 Another approach to division Instead of thinking of it as sharing out a number, division can also be viewed as finding out how many groups of the second number (divisor) are contained in the first number (dividend). The division sum remains the same in both sharing and grouping. 10EETS SW 10 ▽ Introducing remainders In this example, 10 sweets are being divided between 3 girls. However, 3 does not divide exactly into 10 – it fits 3 times with 1 left over. The amount left
