Asked by DaisyI would round it up or down then add / subtract the amount you rounded. So £1.95 would be £2 and £9.95 would be £10. £10 + £2 is £12 Then minus the 10p that was rounded. £12.00 - £0.10 = £11.90 In regards to multiplication use simple techniques like. Multiplying by 2 would be just doubling each number. £5 x 2 = £5 + £5 = £10 Multiplying by 3 can be made easy by doubling then adding the original amount. £5 x 3 = (£5 x 2) + £5 = £10 + £5 = £15 Multiplying by 4 is just doubling then doubling again £5 x 4 = (£5 x 2) x 2 = £10 x 2 = £20 Multiplying by 5 is like multiplying by 4 then adding £5 x 5 = (£5 x 4) + £5 = £20 + £5 = £25 Hope this helps :)
